There seems to be a bug where only Crit Chance Boost is not being reduced by spending trophies on my account. When used, the cooldown on it is 3 seconds slower when all of the skills cooldowns are reduced by 10%. Not too big of a deal, but still a bug. I have relogged multiple times in between resets. My IGN is Isondel.
I've noticed similar...
got all my trophy skills to lv.2 reduction... when clicking them quickly; I always have to pause for about 2 seconds waiting for Crit chance boost to tick off the last bit while all the others are done...
I put one more point into Crit chance (lv.3) while keeping all the others at 2; and it seems to have balanced out now.
