Is splitting arrows worth it?  I read a few guides that say it's not all that good since you get explosive arrows later.  I see you took both.  Good idea?  I have only spent maybe 4 or 5 skill points because I don't know what I should take.  
I think I have ranger strength at 3 or 4, lockpick at 1, mana efficiency at 1, and maybe 1 other thing at 1 (at work so I can't look).
