Not enough processing power if you're playing this game on console. Also its a genre problem. The "smarter" your opponents get in a shooter game, the more game play starts to break down. They'll use their numerical superiority to their advantage and just overwhelm you....and the game becomes unplayable. Its why so much of the end-game content in Year 1 of Destiny 1 wound up just getting cheesed. Bungie made the mistake of----through a combination of AI intelligence, enemy numbers and durability, plus enemy damage-dealing----making a play environment that was do lethat that turtling up in a corner and chipping away at those enemies with scout rifles, sniper rifles, and rocket launchers was the only practical way to play. You may feel differently, but I'm glad they've gotten away from that...and don't wish to see it ever comeback. I like flying around the game world like a super-hero. If I wanted to feel like a WW1 rifleman hunkering down trying to survive an artillery barrage, I'd play a different game.
