If there's just one kid throwing up bubbles, it's not a problem. A well-timed saber throw pops the bubble, charge in and root, kill them before they can use one of the many stuns they have at their disposal. But just wait, the nerf is inevitable.
TLDR; I don't have much of a problem against 1-2 lolbubblers. But when there's 3-4, it's impossible as a melee, unless you're lolsmashing, of course.
You don't have a problem against 1-2 people wearing bubbles, or casting them? Cause it really on takes 1 competent bubble caster to make sure the rest of the team is all bubble, all day.
