I'm having a bit of trouble with the asynchronous nature of combat. This is not a problem for standard attacks, but certainly makes spells and abilities unwieldy. Even with a cleric and wizard standing idle naked in reserve, they often do not have enough time to appropriately respond or apply spells both offensively and defensively. Add the necessity of armor with their own standard attacks, and it's almost as if they are acting independently of the battle conditions. The shifting melee contributes to a high degree of misses, since spells need to be cast at the edge of their periphery to avoid friendly fire. Action and equipment delays regularly necessitate a healing spell to be cast at the first sign of damage or risk it being cast on a corpse.
Having each actor on their own unique time-sequence with the added potential for each to be altered by interruption and movement, the exact nature of the problem is difficult to discern. The experience is reminiscent of solving multivariable calculus. If I were to guess, I would wager that the problem is with the standardized cool-down and use speed of spells/abilities. I think that they too will need some variation--likely based on spell level and attribute scores rather than weapon type. To reiterate, I'm not sure. I'm just wondering if this is a problem for others, and what their thoughts might be.
