I like the concept of Gambit. Competitive PvE, where you can indirectly influence the opposing team via depositing Motes to summon Blockers. It just turns to crap when you then add in the Invaders which emphasise all of the worst things about Destiny PvP. Given that you pretty much only see an Invader when they have Super and/or Heavy ammo. So as a defender you have to deal with someone who has an Overshield, Wallhacks AND a Super/Heavy ammo... So yeah... Honestly, I'd probably like the mode if there was no invading and there was more things you can do to disrupt the opposing team indirectly. Like if you could send over stuff like those slowing mine things. Maybe toss in a few fake Exploding Motes randomly from their kills temporarily. Traps that remove Super energy etc.
