With the patch coming in a couple of days, I decided to make an analysis of how it will affect various Warrior builds in PvP:
Shoutbow:
The current meta build will become even stronger after the patch. With the new shout and access to more discipline traits it will have more condi removal, AoE healing, AoE buffs and even faster might stacking.
With the banner regen trait the AoE healing will be absolutely disgusting.
Hambow:
With Merciless Hammer and Burst Mastery being in the same tier, Hambow as it is now will probably cease to exist. You will have to either give up on cooldown reduction and damage or the much needed adrenaline generation. But with the ability to max out 3 trait lines you get access to shouts, giving you a new way to get adrenaline.
The new build will look more like a Shoutbow variant than the old Hambow. Compared to normal Shoutbow it will have less condi removal and mobility, but gain the Hammer CC. This build will have everything you can possibly want in a teamfight.
Axe:
Axe doesn’t really get anything in the patch, and with the power creep of the other builds it will fall even further behind. It is hard to imagine it being able to compete with the new meta builds.
Greatsword:
With everything GS related being moved to one trait in Strength, the weapon gains a nice boost. With the sad state Axe is in, GS will probably be the weapon of choice for damage builds. Other classes still do it better, though.
Mace:
Condition Mace build gains a small buff in form of 2 stacks of bleed on stuns and some extra might and adrenaline from Discipline. Will still be a fun build to play, but unlikely to become part of the meta.
Sword:
Sword will have the Arms spec all to itself and it will be the spec to take if you use that weapon, regardless of whether you want to play condi, power or hybrid.
More condi damage for condi builds, more crit and easier to land final thrust for power builds (also thanks to 15sec icd heightened focus in disc). Sword actually looks really strong in that patch.
Non-Longbow Builds:
With CI being unchanged, LB is still indispensable. Even with its damage being nerfed it will provide great AoE pressure.
Maybe with more condi removal options becoming available and the new game mode coming later we will see more WvW-like builds with more focus on mobility and less on AoE pressure.
Rifle:
What rifle?
tl;dr version:
It will still be Shoutbows everywhere, possibly with hammer instead of sword/horn.
