Since I'm so bad at PvP I've just started to use defender so I can try to at least help my team as best I can do I dun defender Titan. Some players reaction to bubbles is amazingly funny. My favorite is when they just stand outside...I'm not sure if they think I can't see out or what, but I just peek out, stick them with a nade and dip back inside. The next most funny is people that challenge...they see my in the bubble with my shotgun and then they proceed to either rush or jump through the top to catch me by surprise despite me staring at them the whole time. So Guardians, what's your strategy when you see a bubble?
