OK, Here's my two pfennings...
I like manning AAA, I said it and I am proud... I would like to see a bigger variety of AA guns...the 88mm would be awsome for those pesky vulch bombers at 25k plus. Would put a bit more sport in the game for those buff bunnies.
Also barrage baloons would be nice to help protect AAA positions, but they would pose a problem, too complicated to code in I suspect, but would be nice...
Finally to get more players in the arenas allow non-paying subscribers to man AAA for a longer term then the current two weeks free. i.e. 2 weeks free unlimited free, then two more weeks free for AAA only. Maybe they would get so motivated they would go into there hip pocket and subscribe.
I guess that's three pfennings...I'll pay up later.
