Great vid, guy. Yeah I totally agree a bubble isn't absolutely necessary, it's just a more efficient way to get it done for some. From what I see on this video you're pretty much doing it like anyone would have done on normal mode the first time they did it (well first time I ever did it). Back then the guy who taught us the deal said everyone should make sure they take care of their ogres with sniper rifles (no one had the touch back then too) so yeah, it's just going back to roots :D. Personally I won't opt for this since it's probably going to waste time (people getting used to it) when I'm trying to crack runs down quickly but yeah maybe on those days where no one wants to play a titan :D. Oh and there's nothing wrong with killing someone's knight for them. I do it all the time it's just better if you don't put pressure on the people in your group who have trouble with such things by letting them know you've got their back. All I do is call out if everyone's knights are dead and if one is loose the owner calls the number and I hunt it down. For me it's better if they get to cover than try to be a hero, chasing after their knight and die in the process.
