Titans have a good deal more health than hunters in pvp. I main a hunter and decided to run IB as Titan for IB gear. Against the current main weapons, it felt like I was taking an extra hit to be killed. Shoulder charge is pretty effective when used right. Try using it with verticality. As a lot of people camp corners with shotys. The base weapon changes with greatly benefit Titans. Increasing TTK will make the extra armor matter even more. Main problem I see with people complaining about Titans being weak in pvp are builds that either don't fit the class well or that simply don't match the players play style. Titans aren't warlocks or hunters. Sure it's cool to be a main battle tank on legs, but it might not be the best class for you. I see a lot run speed Titans in crucible. In my opinion, the speed isn't worth the armor for that class. And I do agree that the ram make locks way too tanky. They need to cap the high end value of armor for the class. But Titans aren't supposed to be ability based either. It's all fists guns and shields. They are like Hakke weapons. Hammers not scalpels, stat based and meant to do one thing really really well.
