well 1st as 1st... althugh I've heard of and played teambattle, CTF is still one of the original gametypes and also has a big variety of levels(in other words there are alot of CTF levels). You cant have teambattle on a battle mode level(cuz you roast ur own team 2), but there arent enough teambattle levels if you get me. And besides what Trafton said is kinda true.
Although I'm all for some wars on Jailbreak or some other styles, definetly worth trying...
