2 easy ways that can stop this 1. Increase the amount of energy it's needed for a Titan to create a bubble <pvp only> 2. Remove kills as the only way to gain points and make caps generate points. A team with 2 capture points should automatically win a match if they hold both points the majority of the match. This bubble tactic exploits the game mechanics the control game mode heavily relies on and that's getting kills to generate points. The fact that entire fire teams can be pitted up against a team of randoms only increases the public viewing of this tactic as a exploit because a team that can coordinate and talk to one another already has the upper hand on a team of randoms and it's nearly impossible for a team of randoms to win. Capping a point should be much higher than a measly kill in control. A kill should only count to someone defending a point and not towards someone going around treating the game mode as a passive aggressive death match.
