Talking about Duels, LV? When did I say this was limited to duels? Never. In duels, yes, the Speed+Absorb strtegy is stupid. I'd be better off using only Speed and running rings around you. That would be funny gor the Spectators to watch. I meant for FFA when I mentioned Speed+Absorb.
In duels, I never use Absorb unless attacked by the Force. Thus, I do take a split-second of damage to health or Force mana. But that isn't really enough to worry about, a slash will take that off. Thus, I regain Force via my opponent, (And I turn off Absorb after the enemy is done) and I lose little health, he OTOH has lost Force Mana. Thus, your arguement is a tad useless.
