I've already made a bug report in game, I just wanted to make a forum post to see if anybody else is noticing this.
Bug: Ferocious Roar (Morph of 'Roar')
For the Werewolf Skill "Ferocious Roar", the 33% speed buff to Heavy Attacks only applies to the second heavy attack after your first fully charged one, and any subsequent heavy attacks you chain in a row afterwards. But, if you do any action between heavy attacks, the 33% buff will not apply to the next heavy attack, unless you successfully chain heavy attacks after the first one. Tested in and out of combat, with the same results.
Essentially, the buff only works after the first fully charged heavy attack, and only if you chain consecutive heavy attacks, with no other actions in between.
Essentially, as it currently functions, the Tooltip should read:
For 7 seconds, after a fully charged heavy attack, your next and all consecutive heavy attacks are 33% faster.
Not sure if this is an intended feature of the skill, but if it is, it should be clear from the start, because my first heavy attacks (fully charged at least, hard to tell with medium weaves) were never 33% faster.
Sorry if this wasn't super concise, but I wanted to make sure I explained it well. I don't have capture software to show what I mean right away, so if someone want to test and record it themselves, please do.
