Ask an Aran thread.

Like 3 1/2 seconds.

Eh that seems like enough time to chain a pretty large combo in a place like oblivion guardians, even killing at a good rate, but I see your point that another map less damage for a bigger combo could be beneficial too.

It'd definitely be interesting if they designed a class like that, they'd focus on more stats than just pure attack like all the others, sadly with the endgame maps now it seems like it wont be that way with Aran.
