And don't forget a "Battle Priest" is also a nice build ! My favorite one !
I'm currently playing such build, now almost level 27.
Warrior skills I take are Rush Attack, Whirlwind, Thousant Strikes, maybe later on something else too...
Priest Skills I take are Charm, Summon Ghost, Summon Demon, Summon Mastery, Master Herbalist, Life Tap, maybe Blind if I've too much skillpoints later on .... and in the beginning I take Summon Undead via a yewellery piece that gives 1 or 2 points in that skill, but I focus on the Ghostly Ghosty
I prefer to focus more on specific skills (specialize), especially those skills I really love & gonna use often.
But to be honest: that's also new for me ... in the past I take too many skills because I couldn't choose between them* and it became "a mess"
* that's the problem when so many skills are freaking funny or lovable !
