People are hiding in bubbles and sniping fleets of all levels. Just saw a level 95 in a bubble sniping a level 50's fleet of sawfish with a ghostcrawler a bit outmatched i think. The lvl 95 was in a bubble. It discourages the low levels from continuing on, some have even stated they were thinking of quiting game as it is one sided. I think if you made it where if you are in a bubble and hit another players fleets your bubble should pop just like if you hit a base. Maybe this would cut-off some of the cowardly pay of sniping fleets and hiding in a bubble. Would make it fair for retaliation.
