Nice of Masuda to finally put it on the official record to silence the apologists, even the dev themselves have admitted Dragons are overpowered and this is a long needed intended re-balance for them. I like this game but there has always been a severe type imbalance present ever since Gen 3 which has empowered some setups too much.
Although it's still to be seen if some of their observations may have only been at the surface level or outdated because whilst Ferrothorn and dragons were vermin on a level of Geodude/Zubat random encounters in VGC, a lot of people could probably tell you Thundurus is equally guilty of killing the viability of most things more recently.
Fairy should be weak to fire attacks aswell, a bit too strong at the mo with only Steel and Poison types able to score SE hits o_O
Fire is OP anyway, and X and Y doesn't seem 2 be doing too much for them as of now, but I'm not sure what the Makers are doing creating a type that only Steel and Poison are good with. Hyper OP Muk FTW??
