I'm having a lot of issues when I fight mages that use ward. If it's 1v1, I can just wait til he drops it, but if it's me vs 3-4, I have to miss a lot of opportunities dodging spells or healing myself. Its often impossible to get behind them. The fight drags on for long periods, my magicka is strained, and if the enemies are necromancers they just rez each other.

Anybody got a solid answer to this?

Bound bow. If you're in a dungeon, there's absolutely no reason you would ever have to fight "3-4" enemies at once. Just use the tunnels. Outside you can simply snipe them.

Fire ball/ chain lightning behind them, trolol. It hits them from behind. >:o

Summons, or better yet Frenzy to turn them on each other. At the very least these will detract attention from you.
