at level 61 now it stays at 5 but does it need to be 72 for +6 or +7 or will it stay at +5
Honestly we need new class mods which give bonuses to the whole team, I'd much rather have + 4% team ammo regen than +34% melee damage for the gunzerker or team gun damage or fire rate for axton or team crit damage%+ or team reload speed on zero's. they're the only type of gear not really effected by the level cap increase yet.
We won't know until we see, but I'd love for blue 72 mods to have +7. If they did that, Legendary mods might be +6.
I think Legendary mods are fine as they are. They're specialised for the class and I don't think should have team bonuses. I think that's the toss up, whether to boost your own damage, skills or whatever with a Legendary mod, or to help out the team with another mod.
I would like to see new mods with completely new team bonuses though. Maybe a specific elemental damage boost for the Siren or Mechromancer, or team movement speed after kill, or team melee range. That's what I liked about Krieg's Reaper mod (team kill skill duration) because it was new. I don't think it's really used much at least not in open lobbies, because you don't know whether others are spec'd into their kill skills, and it can be a toss up as to who actually kills an enemy.
