It took me five years, but I finally have a level 70 character of every class!
From left to right, top to bottom:
Phaelia, tiefling trickster rogue
Shintar, half elf devoted cleric
Ekaterina, human great weapon fighter
Daerys, drow control wizard
Puck, halfling hunter ranger
Ophelie, sun elf oathbound paladin
Shintank, dwarf guardian fighter
Shareen, half orc scourge warlock
I have a few more character slots available, but to be honest I can't see myself creating any more alts right now until they release another class, especially as Neverwinter is one of the few MMOs where (in my opinion), levelling another alt just for the sake of starting over isn't actually all that fun..
That said, there's still plenty of max-level stuff to do on all of my existing characters to potentially keep me busy for years to come.
