Just a fast question.

My stealth and power get so much more xp than armor ever single mp match.
Is it just so or am I doing something wrong or just not doing anything that may affect the armor leveling?

You need to use Armor mode more.

Power and stealth will always level faster in most circumstances since Power is effected by pretty much anything you do - Jumping, Sprinting/Climbing ledges and sliding etc.

Also you'll probably spend more time in Stealth then you will in MA - Just get into more firefights with MA on and it'll level faster but it tends to drag behind.

i had problems with lvling invis...

What actually gets points for each mode though? The amount of time spent in that mode? The amount of energy invested into that mode? What? I don't think it's based solely on kills. I regularly switch to armor mode to kill some one and then switch back to stealth or whatever and end up with like 200 points. But then if I just stand around in armor mode in crash site I end up with 700.

It's time spent.

Ergo spend the whole round in armor mode and you'll get mostly armor xp.

In the demo I used to never use stealth and always use Armour... so my stealth was on level 1 while everything else was max, lol

with armour its time spent plus how much damage u recieve while in armor mode
