Tier list!

In that case, I'm even more confused with your placement of BLM... Considering just how easy they are to shut down. Any class with a stun, silence or knockback can ruin their day, especially with those massive cast timers on their burst spells. Sure, they have sleep spam, but again... Bard. Warden's is OP for getting rid of sleep on healers, and the recast timer pops up long before the DR goes away. And MCH would actually be over them even further than I am, with Stun/Silence and Knockback.

You'd need at least one melee and one other dps on the BLM (or any caster for that matter) to be able to effectively shut them down with the interrupt changes; there isn't enough silence or knockbacks (and stun, but that's not exclusive to interrupting just BLMs) to put them out for long in relation to what they can do over a period of time. And help you if you're running against a WHM/BLM combo, because there's no way you can realistically shut them both down beyond your stun DRs (which only a paladin can do reliably) or split burst damage (which gets downplayed by mitigation).

BRD and MCH, their dps outside of burst is pitifully low compared to a BLM, and they honestly won't make anything happen unless you're against an astro healer (in which case BLM still does that area better anyway). Their CC abilities are relatively lacking compared to a SMN and BLM.
