I stopped using the AC some time ago and I am pretty happy with it. Old school Infitlrator playstyle without noobish and unrealistic insta air dodges.
First rule: You are not a fighter. You are a backstabber. Pick out weak targets (finish kills of players who are repairing) or high priority targets such as the jesus mech (The Engineer).
Second rule: Once seen, run and hide. Unless it is a pubstomp or a noobteam against you or just a single player yo ushould probably hide and engage again. Wait for your team to engage or be engaged so they draw the attention of your opponents to them so you can do your job and backstab.
Third rule: Never stay at your teammates or in the deathball. You are an A-Class .. so pretty weak. You are fast so use your mobility and stealth to disengage teamfights. Remeber, in a teamfight your job is to backstab and yo uare fairly easy to hit in a teamfight (even unintentionally and while stealthed) by the never ending explosive spam of HEATs, TOWs, GLs, EOCs, EOCPs, etc. etc. etc.
You want to look for a spot where you can deal damage and have an escape path ready. Once you are seen and the whole enemy team chases you ... pray that your own team is clever enough and chases the enemy team, dealing damage while you either outrun or outmanouver your opponents. This is a rare case in pub matches or mid-low MMR matches so you better team up with a good friend of yours to guarantee atleast one competent pilot in your team.
Two highly skilled players are enough to win any game in low-mid MMR matches with ease. In high MMR matches it might be a bit harder but a well coordinated due can almost outplay anyone. However, the teamscore is what matters in TDM. So even though you are 10/0 .... if your team is 0/13 each then you can be as good as you want, you will lose 10/40 due to stupid teammates.
In case AmpliFIRE and Rasti say something to you. Yea, these guys had an incredible awesome due coordination.
By the way, Rasti has now 3500 hours in ARK after he quit Hawken. That is more gametime than he invested in Hawken AFAIK.
