Armor mode... I think it should work the exact same way it does in single player. That is to say as a "shield". If you have energy, it will be drained and you will suffer no damage to health, wherever the shots are landing. Currently, it just lessens the power of incoming bullets. It is fine in theory. In actual gameplay things are totally different.
Who didn't get OHK'd when in armor mode by a single SCAR bullet to THE LEG? I did, several times, when not lagging. I had a full energy bar and was in armor. So seriously, WTF?
If it worked the way it does in campaign, armor would be indeed much more efficient than it currently is in MP, BUT it would be balanced since you'll have to save energy for it, and this way people could not use the classic technique: "I run around randomly while cloaked til I see someone passing by. Then i turn into armor and empty my clip. +100. Now let's find someone else". Yes I do understand that my idea sounds like "make armor OP plz", but I'm pretty sure it wouldn't be, since 1°) Everyone would have the same armor (thank you captain obvious) and 2°) It will require much more advanced management of energy, because currently it's more like "I hear bullet coming, let's switch to armor even if I have 10% of energy left". This works now, and wouldn't with what I suggest, since your shield would be down in half a second.
Finally, it would make games more fun since everyone won't be using cloak permanently as it is currently the case. (let's be honest, 80% of players use stealth 10 times more often than armor, me first).
Does anyone agree, or once again am I going to get beaten to death?
