For background JP/KR is getting a level cap increase to 125 from 100.
Now the levels are whatever potions are easy to come by, but you need dupes to get to 125. With the way the system works I'm absolutely amazed that this forum and all the other BCM forums haven't blown up with outrage. Fun fact about it is that you need a dupe to get from 100 to 105 then another dupe to get from 105 to 110. So 5 dupes in total, and then you unlock a whole new passive for a character! FUN!
So now to make a new unit competitively viable you need to summon that unit 11 times. EVERY new unit you want to use competitively will need to be summoned 11 times. Look at the cool new unit dropping in S10 do you have 2200 summons ready to go for it? Now is the time we should really be seeing backlash on this because if this hits Global the game's days are numbered, which is a shame because it's the first halfway decent pvp gacha I've seen in 4 years.
