Help me pick a DPS!

[Zari]

Best pick would be MCH or BRD as most people have said. BRD probably moreso than MCH though since MCH does have a rather strict opener/wildfire rotation. BRD is mostly a reactive priority system

[ruskie]

For the style you want BRD and to a lesser extent MCH. Bard is keep up 2 dots, 1 self buff(that for the most part you will always auto refresh anyway), pop cooldowns as and when they happen(or save them for burst if you know the fights), otherwise react to two RNG procs - one of which refreshes your self buff.

MCH is use ammo when available for the most part which forces combo procs so technically once you have ammo you have a set rotation, when you don't it's rng for one proc. One dot and one self buff to keep up as well.

Pick the want you like the most regardless of how high your dps can get.

If you want to obliterate stuff, pick up a NIN, fastest DPS in game. Also extremely easy to use.

Should really give SMN a second chance. It isn't hard to keep track of everything once you play it for a bit and has a lot of ways to play optimally based on various situations due to Aetherflow and the Dreadwyrm Stance as well as swapping between single target, multitarget and AOE.

OP, it really depends on what you like to do, such as are you more of a ranged person, melee, or indifferent. To me, Ninja gives a good bit of versatility due to their movement speed being innately higher than the other melee plus they have ninjitsu that you can weave into your rotation to vary things up a bit versus spamming your combos.

I would promote a ranged melee DPS class in this situation. BRD/MCH have more of a priority based system than a rotational queue. This gives you the most ability to have some options to your fighting. MCH have good initial/steady DPS whereas BRD is more bursty. If you raid I would use BRD, if you are more casual I would use MCH.
