Hi all. I'm playing PL for few months and I didn't really know about dual specing but when I saw bears with bows, mages with swords etc then I was amazed. I have my bear 53lvl pure str and mage 40lvl pure int, and I'm wondering of doing something with them. I'm thinking about making bear a tank or to give him a bow and I'm also thinking about making mage a pally with shield. Right... but I don't have any knowledge about that. Can you guys tell me:

1. What should I do with my characters?
2. What stats should I take?
3. What stats are the most important for them (I mean hit, dps, armor etc) ?
