Honestly have to agree. Things start to get really cheesy when high tier teams start fight stalling for the whm lb...
I have no problem with the damage/heals/stun, game changing lbs are fine, but its sheer potency feels much more in line with a 120 cd.

Miracle of Nature being incurable isn't that big a deal imo. It adds an additional level of threat to a dive, gives you a defensive option for mitigating burst strats, and helps break up the potency of some jobs. I do think however that it should not be as spammable as it is now. Player ability timing should be rewarded, but with a 25 sec cd you can kinda just throw it out and get another before the fight ends. Id say 35 cd.
