I hope of 2 thisngs from this post, 1: that someone who's done this already see's and knows' exactly what I'm saying, and 2. that someone who hasn't seen this done get's what I'm imediatly saying.
I've had a Shadow Priest for going on 2 years now and only just recently realized that by taking the Shadow all the way through the tree selectivly (maybe even with respecing) and collecting the valueable points and then ditributing the remaining 15 points into Disp.'s Unbreakable will --- icreaces Dmg & Healz of instant spells by 5%
Improved Inner Fire- Improver Power word Fortitude so on like this just filling them up till I get to the Good one's at the end,,
Inner Focus---- see on plans
Improved Power Word Shield! and that's the good one really,,,, Inner fire works great, and along side this Improved Inner Fire!
You can see where I'm going with this but after you've spent 15 in Disp. just after getting SHADOW FORM (which I love btw) you'll still have 5 pts. left in the end to finish up you Shadow tree!
It worked great for me and it's the Most fun I've had in any MMO rpg based game Ever!
P.S. always remember too:
Considering priests in a group normally fall into a support role as healer, The three talent areas of the class are Discipline, Holy, and Shadow. Of particular note is that priests that devote themselves to the shadow tree are very frequently regarded as a separate class altogether. The damage capabilities of a shadow priest are exceptionally high compared to the other two trees, and they possess a modest amount of UTILITY VALUE as well. With the rise of hybrid healers, shadow priests have become a very accepted part of WoW culture, and are very prone to melting faces! :)
