I've finally found a couple of fellow gamers willing to give Ars Magica a shot--I've had third, fourth, and now fifth editions sitting on my shelf unused for years, but my particular group has hitherto been D&D-centric. Although I understand 5th Edition to be streamlined and by all accounts Just Better, for now we are going with 4th Edition which, being available for free, is readily available to everyone. My aim is to share my fascination with the game--maybe later set the hook and move on to fifth ed.
I have seen here and there rather strong criticisms of 4th Edition combat for being cumbersome and for giving advantage to, I believe, a naked man armed with a stick over a fully armored knight. My question--are there any house rules floating around that address these concerns? For that matter, are these concerns game-killers, or can they be safely ignored for the time being with a little light humor and emphasis on other parts of the game?
