Doesn't seem evident for me. But I do absolutely agree Vampiric burst should intend (by feel) to give you a sudden urge in power instantly.
Why is it a bug, if I may ask? It doesn't come across as a bug for me but something that helps the feel of playing as a werewolf.
This issue isn't unique to Silver.

Some notes:
1) I mentioned a lot of characters/abilities, but not all of them. I tested all of them. It affects less than half of them, but quite a lot even so. It's inconsistent and feels bad, controls don't respond to user expectation - this is a bug, not design intent.
2) I believe this is a forum for reporting bugs. It's up to developers to accept, reject, ignore, or fix bugs. It is not up to users to call out other users to "prove" something is a bug, or argue with other users about what is or is not a bug. It's especially not a forum to argue "hey you shouldn't fix that bug because personally I'm cool with it". I'd kindly ask you keep threads clear of personal opinion about other people's bugs. If you have opinions about bugs you'd love to stay in the game, please take it to the private suggestion forums. Thank you.
