1. idk which server you are on but as far as I know most Shaiya servers have max lvl 80 now.
2. From a grinding perspective your build does not make sense. You are building an UM pvp archer for high lvl pvp. Optimum grind build would be str/dex something (like 7/2) till the point where you can get 500+ luc, then restat to luc.
Somewhere lvl 60+ you should be getting so much luc from gear that you will not really need base luc anymore and restat to dex/str with emphasis on dex
(If you use this build to get to lvl 30 pvp as well it could make sense depending on your lvl 30 gear but then you wouldn't have to put dex after lvl 30 but only str)
3. If you nos for grinding do not put luc at all in base stats. Knockout nos will give all the crits you need.
full luc grind build can be done but then keep adding luc untill you reach max crit rate, and then switch to dex/str and restat when you know your pvp gear. FYI: from both calculations and experience full luc grind build is terrible for lvl 20-27 but it gets better after that.
