Actually in LoU Overpower often took precedent over Mortal Strike if you had an opportunist buff as Slayer. Overpower does a lot for the kit, hits decently hard and really doesn’t need a huge amount of changes. If anything I’d like to see Dreadnaught be more of a staple as it allows for at least some minor skill expression in character positioning.
As for Martial Prowess, we really don’t need more things to buff execute. Between Fatality actually having benefits before 35% now in Midnight, Executioner’s Precision, Sudden Death, and Deep Wounds really don’t need more things that interact with Execute. Add in the fact that only one Hero talent actually wants to press Execute and the other one just uses it as “Better Slam” I don’t think we need more talents to address Execute.
Slam on the other hand has been kind of a lack luster button that we all understand is a need in the spec (a Rage dump for excessive rage without a cooldown), but its previous modifiers were almost never worth taking in TWW and DF. Slam getting a little bit love is good, and probably won’t change priority too much. It just makes it feel less bad to press for the players that are like, “I’ll take a DPS loss before I press Slam”.
I’m unsure how allowing Sweeping Strikes to hit 3 targets really changes any of this. We already use Sweeping Strikes in any multi-target scenario on cooldown, due to Fervor of Battle. You already press Cleave until you cannot any more, than throw in Mortal Strike (actually super important for Colossus), and everything else left over.
Adding a third target really doesn’t do anything, besides make what’s already looking to be the best melee two target cleave spec, even more powerful.
The bigger issue with Bladestorm not feeling good, hasn’t much to do with Unhinged (unhinged just made it not feel as bad to press in single target), its more to do with all the of the cooldowns Arms has available to it on live servers. Between Bladestorm, Avatar, Thunderous Roar, and Collateral Damage stacking its difficult to allow Bladestorm to deal a ton of damage like it has in the past. Moving into Midnight since we’re really just back to WB/CS as our only Cooldown, it will allow Bladestorm to actually deal some decent damage. Add in new functionality of Bladestorm extending CS and it should feel better to press in Midnight.
I mean currently in TWW and Midnight, Overpower is kind of an after thought. If you’re playing Arms for AoE on live servers, chances are you’re playing Colossus which prioritizes Mortal Strike and Cleave before ever pressing Overpower. Frequently during burst windows its not uncommon to only press Overpower once, or not at all. Despite that Arms can do some nutty AoE Burst damage.
And as Greil stated, Overpower currently on alpha has no interaction with Cleave.
Overall I think a lot of the changes they’ve made to Arms are solid. Things like Test of Might, and In for the Kill, that inflated haste values are all gone. Juggernaut isn’t an effect we need to play around. Talents that sounded cool on paper like fatality, also gained actually functionality to be useful outside of 10 minute boss fight.
There’s still things I’d love to see changed like normalization with Demolish, talent shifts for both the spec tree and class tree, more interesting mastery than what we have on live servers and alpha, but for the most part Arms is trending in a good direction for the alpha.
