Is bard dps the weakest?

[Viridiana]

Why is the summoner's fester ability only cast 3 times? Isn't it on a 10 sec CD for 6 casts in a minute?

Those are actually the numbers you took from poster tn2389. I'm assuming, though, that it's because it requires you to be under the effect of Aetherflow, which only stacks to 3, and has a 1 minute recast.

Edit: Which kinda brings up a second point. If the SMN is pre-casting three Aetherflow casts, it seems like the BRD should get some sort of buff just to make things. . .well, not even, because they're honestly already even if I factor in my critical %. Maybe I should leave BRD unbuffed to give the illusion of equality.

Edit to the edit: Just looked at the actual Aetherflow skill. Guess at 40+ it gives 3 stacks of Aetherflow in one cast, so nevermind the whole thing about pre-casting.
