I have gone against the "Titan cheese" before and the answer is simple. Don't attack. Titan bubbles are stationary so if you and your group stop feeding the golden gunners victims and/or shooting the titans bubble to create orbs for them it will run out. If they are pulling this on one side of the map... Go to the other side until it's done. Also it takes a defensive strategy for the Titan-titties to work well so sit back and wait for all the supers to ware off and let them come to you. One last point... A fist of havoc of nova bomb will cost the enemy team dearly due to them bunching up. If well placed your super could give you a sweet "team kill" and please record it for us. :)
