Just know that one has to build up skill points to unlock the best suits, so you can't just jump into a Gundam and trounce your enemies off the bat. I do think that Zeon got banned from using the GP02A due to spamming it a while back though. Typical 'nerf other side plz' crap being tossed back and forth, I always thought. Zeon and EFF both have fantastic suits and weapons.
I don't know why that was, but there was always a lot of complaining about game balance on both sides.which I never got the reason for at any point. They need an injection of players to rebuild after Zeon did some sort of boycott and pretty much brought things to a grinding halt, and a server move last month. Some are Japanese and don't speak English, though there has always been an English community. There used to be up to 80 people online at a time, but I measured less than 20 on the whole server yesterday.
