You'd be surprised. I am already seeing some people opting to replace their SMN or not take them raids. Since BLM now have the title of highest dps, there needs to be a reason to play SMN. Basically SMN needs that something that only it can provide. A BLM can only do raw damage. A bard will always be wanted for songs/silence. Monk now wanted for dps. That is 3 slots filled. DRG got buffed and is equal in terms of Dps to a SMN now (Or so people say), and their debuffs benefit BRD so they would be the wiser choice.

The only thing SMN has going for them is the fact they are the only dps class that can res. I don't hate SMN, I will still play them. I was hoping for a few buffs to them, such as an Enkindle that is worth the animation time it takes to cast it (Yes it is instant but still, 5 min cd? nty). I still say SE needs to either reduce CD on enkindle to match the damage it does OR increase the damage to match the 5 min CD. I don't care which.
