I’m positive they stacked with personal temp speed increases like aspect of the cheetah, sprint etc maybe the groupwide ones are tagged differently to not stack with each other though but stack with single use options.
That’s definitely a concern but we’ve got what an extra 3 or 4 talent points to play around with in the class tree from leveling to the new max? So there will definitely be options for us to path through most of the offensive nodes and then pickup the relative utility we’d like to pickup.
3% AP while minor does also increase the value of AP since Warriors do gain a little more than other specs from gear strictly due to the Armour to AP conversion we also get through earlier talents so you would be remiss to pick anything else since the additional utility and increase seems helpful.
5% leech on Rallying Cry is pretty insane too, it’s already a very weak raidwide the fact that it also acts as a mini vamp embrace is neat assuming people are on target when rally is being used, the speed on it is a bit of a w/e.
I wouldn’t say the Piercing Howl area of effect isn’t that inconsequential since the WoWhead descriptions read like it’s 12y base and 24y BC improved, unless it’s 48y BC improved which would be ridiculously nice due to everyone will always be in range of it.
