Hi,
Rogues can use scrolls and wands with UMD.
Also, In the last updates, they also got enhancements to boost heals scrolls/wands and also offensive casting with wands/scrolls (which the last i find kinda amusing..).
Anyway, due to this, I think and belive Rogues should get Concentration as class skill.
I dont know how PnP works, but with how DDO works I find it fit.
What do you guys (and guls) think?
