And on the lag front, I am impressed, but I had some of the same issues that lots of other games have, rubber-banding, being shot through cover, wondering why perfect shots seemingly didn't connect, etc. and even some MAG specific ones where a few player models would just freeze in place, not doing anything, and impervious to damage.
I can live with a few oddities here and there though, especially with a launch day server and a 256 player game. Domination mode WORKS, with all those players and keeping the framerate steady alone is impressive as hell. Having a respawn that drops 30+ players into the game at once is something I've never seen, much less to have the whole damn group run out into the field to have a huge battle across a sprawling map.
Its good, but you have to look past some things to find the good stuff.
