Interesting thread - I don't think anyone has really analyzed which shields are more effective. If the small buckler gives more frequent surprise ending, then it may be better. I want to say that bucklers tend to be more effective against speedy and light weapons because they can parry more attacks. But against heavier weapons the greater damage absorbing ability of the Wall-shield seems more effective.

Either way, I voted for no shields because in blood gods you've got to be able to defeat the elite tanks in the game or you will never rise higher than 2nd tier. If using a shield reduces your offensive prowess against the tanks, you won't be able to break into the top. I've yet to see a defensive theatrics defeat an elite tank consistently...or even occasionally...or even once in the last six months. Maybe I'll try it out someday...might be possible with the right gear and ranks.
