bro I'm at 4000 and all i see is level 12 and 13 rg, ik that the rg is not op if level 9 in tournaments but when a level 10 player has a level 13 rg on ladder, there is rarely a chance to win (being a level 10) , and people will say that the giant and hog are found at higher levels too, but the giant and hogriders are rares, and have to be invested in over a longer period of time. if the rg was a rare it would be technically balanced
The fundamental point is that a deck should not be built focused on one card. RG counter is very limited, and to stop him without getting any damage on your tower is rare (the opponent is bad).
Most RG players will have support behind RG, for most counters. (Zaps, minions, fire spirits, and now electro wiz is getting popular to stun inferno tower, etc.)
Card is broken, defending it is pointless.
You are right. A problem for every 4k+ guy. But that's not little. There are like half a million players there and like 20% use him. Overleveled is the problem - why don't you nerf that - his rarity? Or lower his range?
