Advice to a Level 32 LockFollow

I just reached level 32 with my lock. Right now my build is as follows.

2/5 Suppression
5/5 Imp Corruption
2/2 Imp Drain Soul
2/2 Imp Life Tap
2/2 Soul Siphon
5/5 Fel Concentration
2/2 Nightfall
1/2 Grim Reach
1/1 Siphon Life

I am basically sending in my pet -> dot, dot, Life Siphon.

I understand this is the best grinding build. But is it the funniest to play.
I basically quest solo right now with my lock, not too worried about groups or instances. Looking for any suggestions or changes I should make.

Thanks for your Input.

what is funniest probably depends on your sense of humor.

I'm guess you meant which is the most fun to play though, strangely enough, the answer is the same, it's a personal preference.

Same thing with food, or movies, or games for that matter, what you may like, I may not, and I like you may despise. play around and see what YOU like, not what the posters here like.

5/5 Fel Concentration is not overkill if you rain Tank or PvP. It's really almost a necessity.
