My main problem is I can't see clearly when a tome active effect is on CD, also, the new longer tome skills CD and page cost, is so annoying to keep track of that, you need to keep in mind that 3 skills of the same tome gives you a extra page, is a lot to pay attention, is super annoying, you do something different and you ended wasting all pages sooner than you thought.
I still, somehow, enjoy my HB, I don't care about numbers, but they kill the fun of the condi FB, and I didn't even use the rest of the tomes when I played it. Right now I am not having fun and I am not in the mood to play another class.
Changes like this should be done by people who actually mains guardians with tons of hours put on it, if not, you need to talk to people who actually mains guardians with tons of experience on it like the OP.
