here is some hope my supporty friend
specifically at level 50 there is a dungeon you could probably grind on until 70
im going to assume dungeons love healers ( i dont know i will find out tomorrow lol)
the 2 hardest grindy levels you are going to have before this
will be 44-46 , if you are smart u will save as many exp cards as you can to this point to just not have to deal with them
at 47 the exp you need to level resets to about the exp you would need to get to level 19 and then slowly starts growing again
there is another one of these exp resets at 86
and so on and so forth to keep the game exciting? i don’t know but i love the system
edit : woops i didn’t read your last message
