Crowd Control

[Raymeo]

Shameless noob moment, but I haven't ventured outside of my first job in this game yet, and am wondering what to level next. My primary concern:

Which forms of crowd control can each job access?

Assuming that by crowd control you mean hindering mobs in such a way that they are easier to deal with
Sleep; Black Mages get an AoE 60 second sleep and White Mages get a single target 60 sec sleep
Silence; Bards get a 1 sec silence (40ish seconds cooldown) and monks get an AoE silence that requires a few moves before hand *aka have to be careful planing to silence as a monk* (i think its an aoe would have to double check)
Blind; Summoners (and i think scholars?) have an instant blind attack, good only as long as you don't make the mob immune to it (easy to do with PLD's who spam flash
Slow; Summonsers, Scholars, Black Mages, White mages, possibly others? (varies from 20-40%)
Debuffs in general i believe every class has at least 1
and that's all just off the top of my head so there may be a few missing or slighly off, also didn't include PLD stuff since i can see you are one xP

If by crowd control you mean only things like sleep and bind, I say doesn't matter because there is no real need for any of them in the current PVE content...
But if you are a PVP fan, BLM is the way to go :P

Warrior has holmgang which roots them with their target for 6 seconds and for that 6 seconds the warrior cannot go below 1 health (they cannot die).
