The pit in its current version, if we put aside the SB, is the only end game mode with challenge. The problem in my opinion is that it’s just a DPS check, it has no strategic, skilled aspect, and therefore interesting to grind. Also, the fact that there is no Leaderboard means that there is not necessarily any sense in grinding, adding a leaderboard would provide additional motivation. Maybe, to make this mode more interesting, we should simply copy/paste the GR, that was a great mode for push, really more interesting than the actual Pit. Wudijo speak about it in his video review of s6, it was really interesting, hope devs listen to him for this mode !
I can’t imagine they would bother after the gauntlet failed so miserably. Not to mention with their terrible balance having a leaderboard will just result in more complaints about balance.
