jamela - I thought it was about the uselessness of drain spells in battle.
I'm using drain spells because of the following reasons:
1. The healer of my team will only have to keep my sap up.
2. It's harder to keep a DoT:ed player alive than a nuked imo.
3. I can wear heavier armor without losing too much hp/sap.
4. It can almost go on forever with concentrate.

5. I don't like to spam spells.
