This tactic is hard to maintain and manipulate. It's very easy to counter as well. It only works well against an inexperienced team. My team has done this successfully many times but we could have stomped the team harder just playing regularly. I've come across 2 teams doing it and it was extremely easy to counter them. Most of my teammates left and I kept getting new ones that left as well. Pretty much single handedly won against them. Don't keep trying to rush the bubbles like a retard.
