Here are my build for each of them:
Mage/Tamer: 100str 25dex 100int
Magery GM
Eval. Int. GM
Wrestling GM
Meditation GM
Animal Taming GM
Animal Lore GM
Resist Spell GM
Warrior: 100str 100dex 25int
Mace Fighting: GM
Tactics: GM
Healing: GM
Anatomy: GM
Resist Spell: GM
Parrying: GM (Tank warrior with 1 handed mace, good idea? it was pretty good and though in the UO Renaissance days)
Magery: GM? (or a combination of Magery and something else? Need help here for the last one)
Feel free to give me a feedback on these builds, any advice are welcome

Oh... by the way I played ''paying'' UO during 3 years, then I switched on a private server for 3-4 years. I know this game upside down but it have been a LONG time since I played it and the performance of the differents builds tend to change depending on how is coded the server...
Thank you
