I think you should try using a different class. My first character was a striker Titan, and I leveled him up to lvl 28 before I made a hunter. I made a hunter 'cause I was like, "Beotches keep killin me wif dere f-ing hunters in Crucible". I regret nothing. The feel of the Hunter is much more good, much more comfortable than a Titan. For me least. Then, just a month or so ago, I made a warlock, and I liked playing as that even more than I did my hunter! I've tried going back to my Titan a few times over this period, but he just doesn't FEEL good to use. I think Titans are great in PvE. PvP, meh, they're ok. It all really depends on the player though. You could have the best gear in any game, the "best class", and lots of friends, but it comes down to you. What YOU feel comfortable with. If you want to, you can try to get better with the Titan in Crucible. Or you can avoid the Crucible altogether, and continue to use your Titan. Or you can make a warlock and/or hunter if you haven't already, and try using them in Crucible.
