They add new season slots but forget about players with max characters ALL THE TIME.  This has been like the 5th time I've had to ask for a character slot increase when they add new stuff like new classes/seasons etc.  Also players who have done every season still have a remaining ticket to exchange with fughar but can't claim any rewards for it.  Image shown below: 

Just make the 150 Failstack, Perilla's Star, PEN Capotia repeatable rewards through Fughar.  Also maybe even add Floramos accessories.

Floramos all the way! :) And enhancement system for Floramos to get to TET.

Why though ? The character slot max is already a lot higher than the number of classes in the game. And they keep adding slots when new classes come out.

They add a slot when new class comes out not every season otherwise we would have like 50 slots. If my lazy ass ever finishes up making 1 of ea class and get to max slots I'd just save one slot for a seasonal spend the what 4h to finish season collect rewards and delete that one since its just gonna be a useless double.

Correct.

Season is useful for new players. The rest create a new character for seasonal rewards and then remove it (previously transferring the items to another character).

floranos, yes
