Well as a years-long AA player on the server, I'll say this:
If you've been playing there for years, then you'd UNDOUBTEDLY know that having AA at F is absolutely NOT WELCOME. It has been long established that AA should ALWAYS be covering D at the very start, then ONLY A/B/C for the rest of the round. That is an ABSOLUTE and NON-NEGOTIABLE. Anywhere else is considered wasting/camping the AA because it is the single most important asset on the map. It determines the enemy's air capabilities which in turn determines everyone else's.
What you say STRYKER did is not out of the ordinary. If you waste the AA, you will be warned many times over first. From him and from everyone else too. If you choose to ignore these warnings, then yeah, you will be kicked. This has been a longstanding thing and it isn't new.
So no, STRYKER is not an asshole. You willfully chose to ignore calls to get away from F, thinking it was just a preference when in fact, it is an established rule. Messages constantly scroll in the chatbox on the server. It is well-known.
I'm sure that's not what you want to hear, but too bad. I'm not shilling for STRYKER or AARP either. I have my own quarrels with the shit they allow there (hi RedKilla <3), but their very apparent rules on AA is definitely not one of them.
