Well people as a whole will flock to the newest class for a boon then return back to what they were doing unless it becomes the new flavor of the month. But I know people that would go sam regardless of what type it is just because its samurai. But regardless of how loved on class or job is I think overall best practice would to release them in a 3 type sets or 4 set if you want to mark range dps and melee dps different. So that instead of every person at cap leveling acn (which worked out decently well since the jobs were split but exp was still being gained) people would rotate between them. So one of each type the only issue with that though would be if the design team for battle/character design are the same team and is small unless they assign each design by sole indivduals then kicking it to testing but I imagine that would take even longer.
