Necro Early Gameplay

[ECDubz]

Hey guys i wanted to post on here because im having issues on my level 5 Iksar Necro. I find i am being forced to kill yellow mobs because the blue-white mobs only give 1% experience and when i end up going after the yellows they are tough as hell and i can pretty much only kill these by burning through my mana pool and possibly some health because i don't want my pet to die because of loss of DPS.

Is this normal for the experience penalty for Iksar/Necro? I know its -30% but it seems like 1% a kill at lvl 5 is a bit much and I might be doing something wrong. Let me know your thoughts on this.
