[Autotune]

It is possible on some mobs, depending on your gear and their levels. However, a string of interrupts and bashes will ruin your day (which happens often on this server). If you have a cleric healing you also or druid, it should be fine for those periods.

A necro will never be able to replace a cleric and/or tank for groups that want to be able to constantly pull. Better to do what necros do best, increase the efficiency of a group and help CC when needed (this includes off-tanking).
