I'm a Titan and I have actually been doing better than I usually do in other FPS as I have coming out positive in most of my matches so I think Titans are good. Try to make sure you have gear that compliments each other as it will help a lot. So don't get rid of old gear that has good upgrades on them as they can be valuable in the crucible. For an example I'm going to keep my fully automatic shotgun until I find another like it but more powerful as it is good in the crucible.
