Why is goblinball limited? Some players can go to battlegrounds and destroy people, but yet, others with low gear , can't. There for, it would be silly to limit for them goblinball up to 5 matches per day.
Because if it wasn't limited people would play it a lot to get symbols of Gold and flood the Gold market even more on f2p servers. If you want everything to cost even MORE gold.. Im sure devs could remove the limit
