This is a good topic. I can share all my secret builds. I'm just gonna start with what I'm currently using:
All-Around Bow Ninja
Pros:
-Deals 3x damage than most of the ninjas when it comes to purely dps.
-Unless the boss have stun, you can tank all day even with boss/mobs that attacks so very fast and accurately.
-With the right equipment, you can farm mobs efficiently well(will post below).
-Can redirect attacks from boss/mobs to me.
-Can heal allies.
-Can pierce boss' barriers.
(Since I am carrying all utility xtals,I can revive allies(mini heal), pierce barriers(assault), redirects attack from enemy mobs to me(provoke).)
Cons:
-Eats mp fast(if not wearing the mp cost reducing set).
-Doesn't have evasion, you're dead when against boss/mobs that have permastun.
Build:
Max dex first, followed by maxing crit and lastly str.
