But again, Class revamps started in September with the stat revamp. The WP regen is a small part of what they're doing to classes now (For example Iop and Srams final damage can calculate up to 600% flat damage, The amount of sustain a character has, the ease of resource chipping, etc)
I thought so too, but Sram who are dmg dealers have that conditional WP regen. Pandas followed through with this WP regen system, then elios just came out of nowhere.
Idk if you realized but you get a reward for WP regen. Srams get additional base dmg, panda is gain/removal of resist, Iops/ cras is final dmg. The reward is the "niche" , the method to get the reward not so much. Well I wont know for sure till the eni/sadida revamp happens. If eni/sadida get natural regen, then thats the new standard, and sram/panda are due for a revamp a coupe years from now.
The stat revamp was really to make mob stat balancing easier. In the old system i believe they wanted to cap % dmg at 1000 %, but that made it harder for them in the res/hp area of mobs. Also Azael noticed we like to see/do big dmg values so that's was another reason. It was more for the players satisfaction and game development, than class focused.
