I've been pretty happy shooting Grunt Fireteams, much less HI or TAGs. I mean, it gets better the heavier they are, but it's already decent vs ARM 1 or 2. More is just a bonus. If it's getting hacked, that means there are Hackers in range, and you can fry them from behind the Firewall bonus. Yeah, crits are crits, what can you do? I'm not saying they're intensely optimized, but I've been having fun with it, and have had it perform well. They're surely not for everyone.
