Hopefully I wasn't the cause of any of those, Karthus vs Kassadin is a wipeout, as is anyone with good manueverability and adept at playing dodgeball Nevermind the fact I once went up against Soraka down bot and got hosed before the 2 minute mark (including the minute 20 it takes to get out of base). Quite interesting when I have to face another karthus, last one we were a dead even matching, we literally got nothing done the whole game down there.
I actually like playing not just Dominion, but the All Random stuff in the custom games. The one for dominion involves all players being limited to the lower two towers after a random dealing on the champion selection, anywhere south of the speed shrine being fair game, even bushes unlike the random on the Rift. Xereth is great fun on those matches as one of the biggest rules is no backing, via recall or walking back the long way, which makes him an excellent sniper for wounded enemies.
