Nerfs/rotation of cards are hurting combo decks again

It seems to me that every time they nerf or rotate cards they take the time to specifically target combo decks too. Warsong commander, blade flurry, charge, ice lance, conceal, PO. Ben Brode has recently said that charge is an unfun mechanic and multiple times they have said that they don't like OTKs but there is still a playerbase that do enjoy these type of decks. Their bias is so obvious.

Do you suddenly increase diversity by removing freeze mage from the game? No, because people will figure out what the strongest decks are and they are going to play those decks. Its ok for tempo mage, ramp druid, control warrior, zoo to exist for eternity so that can't be the argument either.
