I was looking at the variant rules listed in the Unearthed Arcana, and noticed one that I think could work pretty well in 4th Ed.
Basically it turns the monster's attack into a static number and the players roll a "Defense Roll." I was wondering if anyone who either ran this in 3.5 or had any insight into whether this could work for all of the attacks in 4th Ed.
Specifically, I want to know what is the best way to adapt this to 4th Ed:
Attack Score: of the monsters equal to 11 + Attack bonus
Defense Check of the players being d20 + Defense.
The goal behind this is to have my players be involved even when its not their turn in order to keep them involved and alert as to what is going on.
