Since you're not tier 2 yet.

Weapon can max give you +3 damage.

Armor can mac give you +27 migitation 

So let me see if I got this. Since my weapon his +2; so it'll be 1(base)*(2(slots used) *1(tier level)) +2(weapon skill) and it'll be the same for armor right?

You did it wrong somewhere in those calculations.

Base damage of everyone 1 + weapon damage X (X x tier level(1)) + weapon skill Y.

So 1+2(2*1)+1
