Huh. I thought it was just my luck that every single time Camp Triggerfish was on Ranked it was Rainmaker.
I've played every mode on Triggerfish, but you're right, Rainmaker is the most common, probably because it's a good map for it. I've played Rainmaker in private on Piranha Pit and tbh it's ridiculously broken. I guess some maps really do only feature one type of battle, I mean it was much more balanced when the modes first came out but now it seems like certain maps are used primarily for certain modes. I guess it makes sense, because in order to make everything completely balanced they would have to redesign a lot of the maps even more than they already have, and nobody wants to do that or to have to deal with it.
I'm way too addicted to this game. It's all I play anymore. Send help.
