I haven't been here long but I've been around the internet for a good long while (slut jokes here) and honestly, this place isn't in that bad of condition.
Time stalling moves is obnoxious, but at least tells you the position your opponent feels they're in, and can potentially help in making calls based on their inclinations.
And on shit threads - just because there's a pile of it just sitting there, doesn't mean you have to jump in and roll around in it. You can safely keep an arm's length's distance and spray it with deodorizer too. S'what I try to do anywho
I've never tabbed out of a match and closed it since I don't do Showdown, but I have put my 3DS down on someone taking forever and forgot I was in the middle of a match lol
