what kind of warrior do you plan to be? 2 handed? dual wield? sword & shield? Also are you on PC or console b/c I would highly suggest the respec mod in the Projects section. Dragon Age is a fantastic game but it really sucks if you waste one point or talent then you have no freedom to respec & correct that mistake

If not though & u plan on being a heavy hitter put 2 in strength 1 in dex every time you level. if you plan on dual wielding put 2 in dex 1 in strength. If you want to go S&S either 2 strength 1 constitution or 2 strength 1 dex. A high dex will allow you to have a great defense & evade attacks or a high cons to take lots of damage your choice but i prefer Dex.
Go 2H if u plan to have a high Resistance to getting knocked down & you want hard hitting deadly blows or knocking enemies to the ground for a high DPS teammate to finish off.
Go dual wield with very high dex to stand on your own evade attacks & often while deal massive DPS & carrying the majority of your party's damage.
Sword & Shield if you just want to pull aggro & tank most likely not dealing as much damage as others but taking a lot & allowing your party members to exploit enemy weakness from behidn while you keep enemy focus.
Hope this helps, any more Q's let us know & Merry Christmas!!!!!!!!!!!!!
