So i've noticed a glitch with the titan Melee, where when the fist makes contact, only the burn damage will take effect. It's happened to me numerous times where I will punch the enemy, the sound of fist making contact will trigger... and I watch their shields start to slowly deplete. I've talked to numerous people who can vouch this has happened to them too. I mean it's bad enough titans get t-rex arms to start with but combined with this, makes then practically useless.
