Based on preliminary potency numbers, rogue and ninja weapons likely have lower than average damage values. Probably on par with, or below Archer damage.

The number of buffs, debuffs, cooldowns and attacks suggests that the ninja probably won't have one-size-fits-all rotation and they may end up being pretty flexible. For example, if you wanted to keep all buffs/debuffs up, I don't see any ninja touching Aeolian Edge finisher. By the time they even get the chance, they'll be stuck refreshing a timer. Luckily, Raiton seems to address that issue.

But there's also the fact that we don't have any information on traits yet, and those may extend the timers a bit.
