Is it possible to revamp Arcanist?

[Ryel]

Is it an actual DoT effect limit or is it a visible on the status bar thing limit?

Both, Mobs will have 30 visible DoTs unless you change your settings, but you can still apply more and even if they are invisible using Fester will let you know that you have them applied. Mobs do have a hard cap of 60 DoT effects however and anything over that will not apply and fall off.

I don't follow what you mean by a 'buff' class. Arcanist has all of one buff (Eye for an Eye) and the rest are debuff DoTs. The class with the most buffs is conjurer, but then that's part of their role as healer. Arcanist is a DD first and, at best, a half-arsed healer until they equip Scholar, and even then it's not as much of an improvement as it should be over White Mage, though that Galvanize buff is sublimely obscene. I don't think you understand how to fully use arcanist's varied talents.

Once again i believe he meant to say DEBUFF class, as in he feels ACN needs more damage outside of just DoTs in the rare event that a mob hits the 60 DoT cap and no more are able to be applied, essentially at that point a Summoners damage drops considerably as they will only have pets and Ruin II
