your build should work fine for all pvp contents. you can change lich with wizards to be a bit more tanky too.
its a pretty standard setup for magsorc in pvp, so works on bgs, open world and surely also in IC. also npcs in IC will die fast enough with such a build, if telvar farming is what you want. for telvar farming by killing daedras, i would go for lich, since npcs cant crit and therefore wizards is senseless against npcs.
