Yeah my PC has evolved from 2e to 5e. I disliked the way 4e shoe-horned me into having certain stats to avoid being awful but I have now reverted to my 2e/3e stats for 5e and I am much happier. However, 4e did give my PC a wonderful shadow mage feel (warlock/shadow assassin hybrid) that has been tough to replicate in 5e. I like the Shadow Lord (although I'd rather shadowy escape was a hybrid between misty escape and the monk's shadow step) but there are not enough of the classic shadow-themed spells available yet to really satisfy me.
