Nah, cooldowns are actually very long now. Grenades now have a 1:20 second cooldown IIRC. I think I read somewhere saying super recharge is about 7:30 minutes. I would say I had some good games and only got my super once when the game was about to end.

Feelsbadman. I like the lack of grenades being spammed

Yes I like less grenade spam as well especially compared to D1 but my only problem is supers. You only get your super at the very end of the game and it turns into a clusterf[u]u[/u]ck. It would be better if you had the chance to get your super around the middle of the match and maybe another towards the end.
