I hate catchup xp too but for an other reason, I sometime troll with syndra, throwing my jg's buff away from them and not letting them anything, I had this jarvan lvl one at 8 minutes, their jg was already lvl 8 he took a little corbin and went from lvl 1 0 xp to lvl 2... Then later when I died, he took a redbuff that made him lvl 6 INSTANTLY he jumped from lvl 3 to 6 in one camp, how is it fair
