In Your Experianced Oppnion

What are Preferd merits for nin?

im thinking 5/5 Doton/raiton for slow and paralize ninjustu, make them land better? or 5/5 Subtly blow

Ninja Tools Expertise for shure *I know Yonin, but im shure S.E will edit it so its not 100%, and it wouuld be nice when useing inin then, doton or raton San..

*Bleh Nin merits suck*

p.s is Sange any good?

I guess it all depends on what you want to do with your ninja. Personally I'd do 5/5 Subtle Blow and NTE and put the rest into unlocking San spells. I never use them personally but if you solo a lot it could be worth unlocking them all and giving them some boosts.
