Frenzy Stack Bug.

[Sylvari]

My pets aren't getting over 2 stacks.

Reloaded. Changed pets. Change pet specs.

I did pick up Assurance last night (Normal). I'm wondering if its a bug which is resetting/reducing frenzy. I'm at work and haven't tried to remove trinket.

I tested myself with AoC last night and today, both allowing me to stack frenzy. It may be a pathing issue, in which case try and best describe where you were, maybe include screen shots, and report it to blizzard for QA recreation.
