The real question everyone should be asking is are titan players just better at melees or are titans better at melees? I can almost never out melee a titan but most of the time I think that's just because the person playing the titan is so much more confident in spamming the melee button. The only time ghost melees really happen with me is when it has something to do with strand and even then its not that big of a deal. I also don't use a shotgun much so I don't melee as often as some other people. It does look pretty silly when you lunge and bounce back like you hit something that you didn't hit.
