I have this idea that class event should give “generic” class xp as token, or any other kind of spendable token which could be used to level up any class.
I recognized I almost never use the event class in class trial, especially if I have that class at level 100 already. As more and more of my classes hits lvl 70 or 100 the class trial event becomes less relevant for me, cause I get totally useless class xp from it. I buy only the 1 tier from the shop for the enchant potion and I do as many battles as the RNG gives me but I don’t have the reason to go for all 8 reward stages.
However if the event reward would be class xp which could be used on any class I would be more motivated to go for maximal reward and buy more tiers in the shop.
