I was thinking of possible changes to RoE and FoW since I feel that the former isn't really as good as it could be and the latter remains utterly useless since the 2.X series.

For RoE, the fact that you don't get the extra 10% less damage taken buff until after the initial hit doesn't really make it any different from FoE for most raid-wide attacks, let alone briefly tanking a boss. And considering that monks have TK and PB, on top of GL now lasting 16 seconds, there's not much point in a refresh since if a boss is gonna jump it'd be better to just use TK (so far, I've only benefitted from the refresh effect during OV4 just cause damage still goes out while the boss is gone). I think it'd be better if the defense buff were applied right away (or even increased) in exchange for the GL refresh buff being removed completely and giving it a longer cooldown (since you really shouldn't be using it unless it's an emergency situation).
