Patch 2.1 is close, soon a swarm of "OMG OP, NERF NOWZ" threads are incoming with the usual end of the world threads in increased volumes. Such prediction is not a speculation, most of us have seen it happen in every single MMO, and I'm 99.998% sure it will happen here without any doubt in my mind.
I have no idea how SE are going to handle it or if they have a special system in place for it. However, there is one thing any FF 11 player knows, when SE nerfs a class/job, they don't just nerf they literally break it into uselessness. If memory serve me right, other MMO devs nerf hard but they have nothing on SE.
Personally, I have always been against any kind of nerfs, this include the upcoming Bards nerf. I rather see 8 Jobs buffed than see one get nerfed to the ground (or even a slight nerf). PvP does not interest me personally as I get my fair share of PvP from Dota 2. My fears are nerfs might reflect on PvE, and suddenly a good wanted job in Coil is no longer wanted due to a nerf that happened for PvP. Veteran MMO players have also seen this before, DEV decide to nerf a class for PvP and end up turning it useless for PvE.
I really hope & wish I'm wrong.
SE, please, Buff and don't nerf. Please, be gentle.
P.S.
"OMG SMN OP, DOTS AND KITE WHILE GRUDA EATS FACE, GGWP SE, NERF NOOW". I called it.
