MMORPG.com Atlantica Online Correspondent Andrew Corpuz writes this look at the issue surrounding the double Monk issue in Atlantica Online and gives some possible solutions.

1) Create a Penalty for Holy Guard; turn Heal into a DoT or Debuff

Summary: Recently in Korea, the heal from Holy Guard has been reduced. However, this has had little effect on double monk strategy. The real benefit of Holy Guard isn't its heal; it's the protection from magic. Currently, players almost automatically Holy Guard their front-line to protect from an opponent's Viking's Freezing Axe / Ice Ridge. This, of course, isn't the case if the opponent has no Viking or if the player is under greater pressure such as stun, however, if Holy Guard's heal is turned into a DoT or debuff, players will have to wonder whether or not the protection from magic is worth the Dot or Debuff sacrifice.
