IMO there are 2 main problems in the most common decks on the first days:
- Mana discount/cheating: Some of the most problematics decks (mages with Incanter's Flow / [card] refreshing spring water[/card] , rogues with Efficient Octo-bot or Preparation and lock with the new weapon/stealer of souls.
- Little interaction with minions, the meta is too combo oriented. Besides of spell mage, quest lock and garrote rogue, there are other combo decks like diferent variations DH, corrupt shaman (this is more inconsistent). Face hunter, agro shaman and quest druid aren't combo decks but they don't interact very often with minions.
