I need help choosing my last class!

So, you probably might know that I'm and all out Warlock fan. So, that kinda ended up in me having 2 Warlocks, one a Voidwalker and the other a Sunsinger. Now, I don't want to get rid of either of these Warlocks, and I need help picking my last class. I can't choose between Hunter or Titan, plz help. Plz tell me what class I should pick and what subclass too! Thx in advance!
