returning player help

Hi! i haven't played in about 1.5 years but wanted to try again but just on 1 character only. 3 raids a week max (i asssume that's stil lthe max for 1 character). wanted advice on what character to play.... my top 3 fave was bk, rage destro and redlancer.

i have a 9/7 stone on bk but i feel the itch to play rage destro. basically looking for easy to play with at least 1 skill that has big numbers. any advice on what i should do?
