It leaves you 1 shot the instant you touch it dude. It definitely hurts you. It's a problem because of how almost all modes have some sort of objective play and they flat out are the best option for playing defensively. It's easily possible to shut entire teams out of rooms for objectives by having a few titans hold circle at entrances. And how quick you can get cooldowns, they give overshileds to the entire team as well as being able to have more than 1 active at a time. That is why they are a problem. Personally, if they left the cooldown alone, reduced health slightly, and made it so you can only have 1 active at a time, it would be fine.
