I'm slowing down on it for two main reasons.
1. The whining. You can't play PvP with random people and avoid getting flamed over nothing anymore. "Omg" is so overused these days, and you get called on for doing things like "spamming" or "running" whether you're actually doing them or not. Poor sportsmanship is rampant among the GC community, I've actually been flamed for saying "Good game." when I won a 3-0 match. There's stuff like this in ALL online games, I understand that, but I've never seen it this bad in any other game. 1v1 is a load of poo; I don't know who thought of the idea, but I'd like to meet him someday so I can have a nice little chat with him. Seriously, all of that just got to be too much, I can only handle it in small doses anymore.
2. I got a full account on Elsword recently. After that, it's hard to go back to Grand Chase.
