My issue with the game; sandwich

I can't say I've had the degree of sandwiching you've had, but I do get into these situations somewhat often. I always CAUSE these situations a lot because it's usually an easy way to wipe multiple squads who are all low on shields/HP. Bangalore is great for this, I'll tell my squad to chill for a few seconds and then we pop double smoke and do cleanup duty and pick up 5+ kills easily.

I think this kind of thing will happen less frequently as the game ages a bit and people get used to being patient and watch their positioning. Sometimes you'll just get unlucky though. When I play with my friends we run what we call a blitz composition with bangalore, pathfinder and bloodhound and we play aggressively and try to interrupt ongoing firefights, we all pop our ultimates at the same time under double smokes and we try to make sure we have guns like the LMGs and Peacekeeper or Wingman which are all very good for aggressive play. Works well, we usually let the smoke linger for a bit then the pathfinder drops a good zipline and I call in the artillery strike and bloodhound gets aggressive since he can see through the smoke. Pretty much can't survive this level of aggression.

I wouldn't mind add-ons to the map in the future to make it bigger...or an entirely new map with a 50/50 chance of which map is selected for the match.
