1. Honestly dont listen to those guys bro. Take it from a 8k+ dps warrior.
2. Just get 163-165 or as close as you can.
3. With that you will miss no specails.
4. Depending on your rotation you will have no problem. Maybe 2%miss on melee and nothing else.
5. Melee should be about your bottom damage. On a single target raid buffed my dps meters go, 1. heroic strike 2. bloodthirst 3. deepwounds 6. When in rotation one of your top priority is to use herioc strike almost every swing which lowers the % of miss on melee and causes deepwounds to tick alot harder. Do not use slam unless procced for insta slam. +use ww and bt every cd. When below 20% only use excicute in open gcd if you have alot of rage.
Thats all the advice i can give you. Take it easy.
