BRD Crowd Control - Shadowbind 40 s CD, Blunt Arrow 30s CD, Blast Shot 150s CD. A bind, silence, and knockback, all on relatively long CD's aside from the silence compared to what the other jobs are capable of. That's hardly any Crowd Control, it's there it's just not much.
BRD Utility - Mana Song, Mages Ballad(lowers damage dealt but restores MP), Foe Requiem(Unusable in 4v4) Mana Draw(Useless) Wardens Paean(the only really useful utility they have, however very RNG related with which detrimental effects will be stopped or broken)
BRD has powerful burst yes but they meet the criteria of having no real CC or utility to speak of while also having their burst stopped by purify. If you leave a bard alone they can kill you. But why would you leave a bard alone? They lack CC resistance so it's also easy to sleep them/stun lock them during their burst window and halting it, or even binding them and getting out of their range.
MCH - Crowd Control 40% Heavy / 12 s bind that while good are sharing CD timers, You can use one or the other but not both and you're likely going to be using the bind more often, Stun /Silence on a shared recast timer. Stun Gun AoE Stun, this is good but its not always best the build up DR in an AoE fashion like this. Knockback that requires close range(can be good can be bad, its a coin flip due to the range required)
Machinist actually comes out ahead of bard in terms of CC in one way, and then not in another due to the fact that a lot their CC tools are on a shared timer with each other or require close range for some awful reason.
Utility - Hypercharge(requires careful use as it can overwrite fullswing but otherwise good), Promotion(you'll probably never use this), Rend mind /dismantle(5% isn't anything to really write home about),Report(actually a decent tool like mana song)
The problem is mch suffers from the same thing bard does, they're very susceptible to CC, they require their own CC to be on the target to do their highest damage, which only requires a cleanse to be dealt with. Their utility isn't that great. But they do at least have a decent range of CC where as bard does not.
-----
Basically they have powerful burst, but they also have a number of problems involving their burst like requiring the target to be CC'd or without purify, they themselves have no tool aside from purify to help deal with CC making their bursts easier to deal with despite being ranged classes. I feel Machinist has a bit more to make it competitive than bard though, they're still both good jobs they're just not the greatest in terms of what they bring aside from their burst.
