Profession-specific finishers!
I like the idea, that would be cool, instead of the usual banner stomp.
If GW2 is all about the style and skin, why not choose that too ? It may be granted as a reward in pvp just like the usual rabbit and dear finishers. And you could find it in PVE with special quest.
I would love too choose among several finisher, according to my style :
Fire ele – burn the ennemy with a pillar of fire and blow the ashes in the wind
Air ele – strike with a big lightning
Minion master necro – summons a swarm of nasty beasties to eat the target
Duelist mesmer – have the target kill itself out of despair
The only point I see is : how gore is the finisher ?
You don’t want it to be a slaughter with blood everywhere so this may be an issue
I’m quite happy with my permanent cow finisher.
