im a 70 warrior with tailoring as skill. but isn't blacksmithing better for me then tailoring cause i can make my armors myself. spended tons of money in tailoring and don't know what is best for me.
Yes BS is more useful to you to use the items you make (weapons or armors depending on what you specialise in later on) unless you like wearing cloth items or want lots of bags? ;-)
BUT...
Smithing is veeeerryy expensive to level as well (more that tailoring i think) and unless you have mining too it will be even harder - the amount of metal bars you need is phenomenal :-(
You might want to consider a completely different profession entirely for you warrior?
Definitely BS as a warrior. Once you're in the higher lvl tailoring, most are BOP items that you can't make gold off of. At least with BS you can use the items.
