A large part of the ogryns identity is debuffing and weakening enemies. This is a great identity, and the debuff playstyle is one of my favorite ways to play classes like psyker and zealot. Brittleness is a huge part of any build that has debuffing as a focus. For example, the rending shockwave blessing on the voidblast staff is amazing for this purpose. It lets you apply 20% brittleness to around a 9 meter radius. Similarly, the thunderous blessing on the zealots crusher does something similar on special attacks, applying 10% brittleness in a 5 meter radius, with a pretty fast usage rate.
The problem with ogryn, is that he has very limited ways to access brittleness, and the ways he does have are not potent. The three ways I am aware of are the shattering impact blessings on both the rumbler, and the grenadier gauntlet, as well as the new brittleness on push talent he is recieving. Lets look at shattering impact first:
It applies 10% brittleness to the single enemy that you direct impact with either grenade launchers projectile. This is just immediately noticeably worse the the psyker and zealots options I listed above. The grenadier gauntlet has it slightly better, as it has better ammo economy and fire rate, but it still has to use ammo to get the same effect as what the zealots crusher can apply to half a horde at once by pressing a button. The rumbler should be similar to the equivalent to the voidblast staff on psyker, and its brittleness blessing should be the same as well. Especially since the rumbler costs ammo and has to reload between every shot.
How to fix:
Change the shattering impact blessing from applying brittleness to the enemy impacted, to all enemies caught within the suppression on the blast. This would not end up being broken on the grenadier gauntlet as its blast radius isnt that large in the first place, but would make the rumbler a much stronger pick for debuffing.
One thing I only mentioned briefly was the new brittleness on push talent. This could end up being very strong, but as of now it only says “4 stacks of brittleness”, and while I assume that means 2.5% brittleness per stack, it could very well just be 1% per stack, in which case it would not be as powerful.
Anyways, thanks for reading. Im just a guy who likes his debuff builds, and seeing other classes get so much better options over the class who has several talents related to it seems unfair.
