Never had any new maps added since its introduction so it became tedious for me, and its unfortunate as the mode can be fun, Id personally like to see a 6 player per side version, the 4v4 concept was from vanilla d2 where even crucible was 4v4 for some dumb reason.
If it had a unique armor set or exotics to chase I think more players would show interest too.
But definitely far far overdue for new maps
I agree. Mostly I like it, but some improvements would be nice.
Your ideas are good, new maps, maybe an exotic weapon or armor (something you could only get from gambit) or at the very least ornaments for legendary and or exotics.
The one part I would disagree on is 6v6. I think most maps are small enough with set enemy spawn size and location, 6v6 would make it harder to get moats.
6v6 might work, if they put in larger maps, with maybe 2-3 enemy spawn locations at the same time. That might be fun.
If it had 6v6 then for sure maps would have to be larger and have a higher enemy density sorry, I should have said that.
Could also potentially have mini bosses that spawn for the trailing team (more or less a catch-up mechanic) that drop say 20-25 motes this could help keep matches closer and more engaging.
