What are the Players and the DM supposed to be permitted to know in regards to rolls/defenses during combat?
I've only played 4th Ed. D&D, so I don't know how it's handled in other editions. However, I've seen it done a couple different ways in 4e games and I'm wanting to know what is commonly accepted as the "right way".
My preferred method is that all attack rolls (Player & DM) are announced. No matter who is making the roll, the attacker asks the target "Does [total roll] hit your [targeted defense]?" and the target answers "yes" or "no".
However, some DMs will instead ask "What's your [targeted defense]?" without telling what they rolled for the attack. Of course, the DM is effectively god in his game, but am I the only one who considers this bad form? Are there any official rules/guidelines to support this?
