I want to try a DPS class

[Thorsparkle]

I'm sort of in the same boat. I've been playing a white mage since launch, but want to try a DPS class for a change of pace (also, there seem to be waaay too many healers for some reason).

My main limitation is that I'm playing with high (250-300) latency... so any class that relies on precise timing, tight burst windows and/or double weaving is probably out. I have summoner leveled up fairly high, and it seems to be OK... but how about other classes?

High Latency, you can forget NIN (Mudra lag) and probably BLM (very time sensitive if you want to be effective on your cycles).

SMN is probably the good way to go if you want pure DPS. Best AOE damage, fair single target damage, and good mobility.
DRG or MNK don't mind latency too much either and you can achieve good dps with both.
MCH and BRD ... well ...
