Tier seems to be Aoe centric, The design goal May be focus on our aoe due to the next raid just having a lot of 2-3 target fights (wcl please stop excluding damage), I would like to repaint the idea of a warrior being a bay blade of death, while also empowering our singletarget.
2 set: Echos of hell
Your Deep wounds tick now damage all targets around it (think like living bomb, aoe pulse every 3 seconds numbers can be tuned up or down if 2 week or 2 strong, remember warrior is capped at 2 and 4 targets
4 set: Reverberation of the dammed
Targets effected by your deep wounds are weakened, making it easier to strike them, Bloodthirst/Slam/Mortal strike now echo to all targets effected by your deep wounds. (can Tune damage, can be 100% can be 25% whatever works, opens up a few trinket options on some fights, like swarm guard.) This also doubles as a singletarget damage inc as your bt will now hit your primary target twice
6 set: Soul cleaver
When you cast cleave or Heroic strike, you cast whirlwind, when you cast whirlwind, you cast rend, and refresh rend on any target with it applied.
Mostly a qol tier set. Whirlwind is very weak right now. Its a lower prio then our instant proc slam, and is even delayed for our slam, having it auto cast can be a fun way to feed both a single target and an aoe damage inc, while staying thematic to the aoe angle this set seems to be, It also fixes the clunk of having to apply rend due to sanguinis, and having it spread while in an aoe pull gives us a boost, due to not having to spend globals on rend. It doesnt have to be at 100% power it can be at 25% or whatever tuning feels apropriate.
I know not all these ideas are winners, but i hope this can provide some ideas for how the set can be changed while keeping its cleave centric nature. I think expelled ideas are good, i just want to put forth some more ideas, and i hope it inspires the community to come forth with there own vision of what a warrior this tier should play/feel like.
