People who think BLM are going to be OP in pvp do not know how painfully easy it is to negate every one of the BLM's casts by jumping through him.

With lag and such I believe it would be even easier to cancel casts.

Melee without mobility will be a problem, so shoulder tackle (aka charge) is going to be pretty useful.

BLM's do not have a usable blink w/o a party member nearby (also not sure if usable while stunned/rooted) and have the lowest hp of any class.

Furthermore: cloth has almost 0 physical reduction.

I can imagine a pali stunbot and monk/dragoon completely blowing up a BLM in the ~6 seconds of stun you get with DR.

DoTs will likely be meaningless, as there is no penalty for removing DoTs. Summoners will be pretty bad unless you can get your miasmas to stick.

VS a no healer burst team they can be pretty good with massive slow maybe.
