7.24b patch for Dota 2 comes off as a considerable nerf to each changed hero and item it changes upon. The official patch notes can be found here.
Item changes bring a nerf to the Bracer, Desolator, Diffusals and to Maelstrom and Mjollnir.
Each item has reductions other than a 10+ to damage for the Desolator. The biggest affector of these changes is to the magic hammers, considered to be the most viable choices in the current meta of Dota 2’s 7.24.
Bracer’s Magic resistance is reduced from 5% to 4%.
Desolator’s armor reduction is reduced from 7 to 6 and damage is increased from 50 to 60.
Diffusal Blades’ Mana burnt per attack is reduced from 50 to 40, now sitting as the same amount as it sat before the annual overhaul patch.
In 7.24b, the item changes can be generally related to the hard-carry meta that procures the choices of Mjolnnir to the fullest, examples being on multiple heroes such as on Lifestealer, Juggernaut, Weaver, almost every ranged hard-carry and more.
There shall be a bigger effect on the overall team fight stance with lesser AOE from Mjollnir usually procured by hard-carries in the current meta. This shows some changes to correlate with the changes made to the hero changes, with the biggest nerf dropped on Tiny, Slardar, Lifestealer and Snapfire.
The Hero changes of the newest patch also see considerable nerfs to almost every hero effected.
Starting with Batrider, he gets a small nerf to the duration of Flamebreak’s burn, mostly an effect for his damage output on low levels in the early game.
Followed with Enchantress, she gets a nerf with more consumption of mana for Impetus, being a constant 65. This shall show obscurity for her damage output as well as her other skills that suffice a great deal on high mana.
Huskar is also going to face a small nerf on base damage and health and other benefits of the strength attribute that drops from 3.4 to 3.2. Topping up with a nerf to the Bracer, his early game would face a more difficult state than before as he is vulnerable to magic damage, currently having lesser means of good magic resistance.
Io sees a nerf to her overcharge regen, with minor drops from 0.55/0.7/0.85/1% to 0.5/0.6/0.7/0.8%.
Lifestealer comes next and shows a considerable downgrade to his stats and, as it already shows, a lower win rate in the current patch. He sits currently at a 48%ish win rate from his previous 53% win rate due to the recent changes. Mjollnir that was a valid build option on the hero has seen a nerf as well as the strength item Bracer. His workload to deal good amounts of damage quickly since the addition of attack speed to his skill had made a good followup with the attack speed of the Mjollnir, but the small changes have made his early game weaker. This has made his catchup to be a viable farming hard-carry role much more difficult.
Nyx Assassin comes as the next hero to get a nerf on his stun duration. It sits at 1.4/1.8/2.2/2.6 from 1.6/2/2.4/2.8. This is supposedly a nerf to the overall higher pick rate the hero has had along with being the choice of the stunner and chaser, his ultimate now having pure damage. A minor nerf overall.
Puck’s Waning Rift cast range is reduced from 350 to 275.
The next bigger hero nerf is to Slardar. He has seen a higher win rate along with a higher pick rate as the current meta makes him the choice for the offlane and semi carry roles. His ultimate shows a big improvement of the overall factor to team fights in the game that provides better stats of chasing with vision over the target.
The nerf comes to his Ultimate, his bash, and mana. There is now 25 usage of mana for his skill Guardian Sprint. Already a hero that has low mana growth, it puts more stress in his mana numbers. The nerf to his bash damage gives way to less abstinence of his usual bash combo that puts heroes into occasions where there are only one-second windows of any action. This combined with a lower point of armor loss via his Ultimate, his damage output will be considerably lower. Bash of the Deep damage is reduced from 60/115/170/225 to 50/100/150/200, and Corrosive Haze is reduced from 10/15/20 to 8/13/18.
Snapfire also gets somewhat bigger nerfs than most heroes in 7.24b with her Firesnap Cookie stun duration reduced from 1.6/1.9/2.2/2.5 to 1.6/1.8/2/2.2. Her Mortimer Kisses damage reduction from 200/300/400 to 160/240/320 also lowers her damage output. Ingame, her viability sat well with stunners as she could dish out 1200 damages along the lines of higher support choices all at the same time being of only level 6. This would be greatly changed now with the nerfs.
Timbersaw’s Reactive Armor bonus armor per stack is reduced from 1/1.1/1.2/1.3 to 0.9/1/1.1/1.2, making him less of a stone on lane in scrims and lower MMR matches.
Tiny also faces considerably larger nerfs in 7.24b with Grow armor reduction from 10/18/26 to 10/16/22 and Toss cast range reduced from 1000/1100/1200/1300 to 850/1000/1150/1300.
His strong mid-game that one-shots most support picks with low health would still pose a problem, but the followup would make him be more vulnerable with less tankyness with the nerf to his armor and to the Bracer item. His early game shall be given a little control in terms of a team fight and his overall effect.
Void Spirit’s movement speed is reduced from 305 to 300, emphasizing his escape on his two spells but mostly to his ultimate.
There is chance for the less tarrying picks to come out front that can face against the main users of the nerfed items now. There should be a noticeable change in the draft due to this with broader viability considering these specific changes to a small part of the successful higher end of the current meta in the game.
Overall, 7.24b brings some balances to damage output, mostly to strength heroes and to attack speed in terms of Mjollnir options. Players would be willing to check up on other builds now that would suffice with a different approach.
