I'm not a big fan of 3 major skill templates.. it spreads you too thin as you don't have enough points to compliment any of them with the secondary skills. Eg. You can doe a ninja/macer/mage.. but for ninja most of the specials are useless without stealth/hiding or tracking for DS.. for macer, you're going to want tactics for damage increase.. for Mage you'll want Eval and Meditation. For a good PvM character I'd reccomend sticking to basic templates. A hybrid is good such as the Pally/Necro..

Up to you.. I have just found it really hard to get the most out of the major skills if you can't increase their potention potency with the complimentary skills.
