I agree that using titan is hard but only in PvP. I feel all classes are almost balanced when it comes to PvE. Also almost all people say that using hunters and warlocks takes a lot of skill. Not true if you use blink. Check your previous game stats and you will see that almost all PvP matches you played had Hunters and warlocks in the top 3 on both teams with titans somewhere near to the bottom. With titans it's a little hard to challenge Warlocks and Hunters as they can blink away to save themselves but a titan can only hope you miss your shot in order to survive.
