A negative impact, at least for me. Variety makes things interesting, I like a lot of the bigger maps, and it's easy to figure out where an attack is likely to go to and come from. People who depend solely on darbars for cues are missing out.
There is almost always a base take plan happening somewhere, and if there isn't, you can start one and probably get the action you want rolling. "Build it and they will come" etc.
I mean atleast do a randomizer on the rotation then.. like the rotation is getting sooo old for me, and puts all the big maps close together. If you only have a 2 week trial and get stuck on BowlMA, then CraterMA, then Oceania, and nothing going on for 95% of the day, than how can you expect off hours #s to increase? We have got to bring the fighters back to the game. Thats where the #s are. For me, im not going to fly to a random base with no enemy and hope one guy rolls. Im not going to jump into a 20 on 1 horde with no friendlies because even in a temp that's boring, and im not going to roll for 1 set of B26s at 19k.. im not going to roll for 1 190D at 15k either. People want battles! I want battles!
The biggest thing this game is missing right now are battle zones where the majority of players are in the action at a given time. The larger maps just dont provide that, and dont provide situations where all teams can find battles at any time with each other.
