Please everyone, don't feed the troll. You'll only encourage it.
After playing the game for a few hours I have to say it's awesome. Not sure yet if it's on par or better then MW:4 mp, that will come when I know all the details of the game and the final version is released.
One thing I like is how the credit system works. You always respawn with enough to buy a small mech/vehicle/aircraft, the more kills you get the higher rank you become which respawns you with more credits. You earn enough credits easily to repair/rearm your mech while fighting (this is assuming you lived to repair), but you have to be damn good for the total to exceed you base spawn amount allowing you to buy more.
There is locational damage, so weapons can be destroyed or the mech's speed reduced. When a weapon is destroyed you can not repair it, so beware if you have only one big gun on your mech.
Teamwork seems like it can/will play a huge part in this game. One mech with a tag laser with two missile boats behind a hill will rape almost anything they face.
One thing I hate is how bothersome elementals can be. You can't seem to lock onto them with SRM's and are very hard to hit. If they become a problem, buddy up and load some AOE weapons (still don't know what is best).
The biggest problem atm is lag issues that many seem to be experiencing. Severs with N/A ping seem to have the least, with many others flashing the disconnect icon every few seconds.
