You're right, actually...I should consider killed warriors for the Hall if they truly had great records (like 100 or more wins, a fair amount of kills, and a championship or two or more). That change will probably be made down the road.
The more I think about it, the more it makes sense (they do induct people into Shrines and such sometimes in real sports when they've passed on). I think I wanted to make it tougher to get into the Hall, so it truly be a rare event. The forthcoming 1.5 patch adjusts death chances a bit, so that warriors may live a bit longer and more may have a chance for Hall consideration.
Thanks, Spags!
