Talking of RNG stuff it took like 1-2 week(s) for my friend to find the challenger in arena back then.

Also for the grindy aps I mean glint set is still there tbh which used to take months to craft (probably still takes few weeks).

Honestly didn't really wanna get into this topic since I got no interest at all but well it started to sound like an excuse when you are strictly against this idea especially when you have those APs I just mentioned exists in the game.
