Lag is what absolutely ruined spar. When the game was first released there was hardly any to worry about. Now it's much much worse. The accounts you can blame the people who are too afraid to ruin their precious record and have to go on other accounts to practice first. Now they caused even more hate on newbies saying if they are good they must be on a second account. Wall sparring and spamming are both annoying techniques, but with experience you should know how to get past them. For talking that is extremely annoying when people do that in spar. Especially when they're losing and than they start saying something like "This is bull ****!" Don't get me started on PC. Let's just say I don't like it. Noob is an overused word on Graal and can often be funny rather than an insult.
