A battle between a knight army and a warlock army often results in a fairly even match. It can be challenging when the warlock has a high spell power and powerful spells, but it's more manageable than when a strong knight hero replaces their army with 3 red creatures from the Dragon Shrine. In that case, the warlock is in deep trouble, almost regardless of their army. And angels completely destroy this balance, not to mention the atmosphere of the game itself.
The fifth installment needs to change something and prove its worth to sell, while the best game of 1996 has long proven its complete viability.
