Meteor in my honest opinion are totally fine. I have a problem when they appear in a chest in like 3's or 4's in a row, and then suddenly everybody in the front field just got meteor rained on. There only known way to counter meteors is with hero's tonic, and the chances of you holding on to one, or it not getting stolen, are pretty slim. 1 meteor is cool, 2 is still not to bad, but 3+ is a bit much, there just shouldn't be that many in a single chest, ever period.
