Back on topic (just 10 for now):
1. Should a character get bonuses or penalties on his social interaction skills (Bluff, Diplomacy, Intimidate, Sense Motive) based on how well the player roleplays?
2. Can a character find a trap whose mechanism is entirely hidden behind a door? This is closely linked to the question of whether a character searching for or disabling a trap should suffer some penalty or even automatically fail to find or disable it if the player doesn't say that he does the "right thing" (whatever the DM defines the "right thing" to be, e.g. half opening the door and using a mirror to look at the mechanism behind it)?
3. Is it valid to charge an opponent along a path that is actually slightly to the side of the opponent (e.g. if your opponent is 5 feet to your left and 20 feet in front of you, can you charge straight ahead and attack him diagonally)?
4. The Cleave off AOO issue has been debated again recently.
5. If you no longer meet a feat's prerequisite, does this mean that you also lose the benefits of other feats and abilities from prestige classes that have that feat as a prerequisite?
6. Should scouts have Disable Device as a class skill (errata has clarified that they do, but that's not the issue)?
7. How does Natural Bond (feat from Complete Adventurer) interact with the alternative animal companions he can select at higher levels? Can a druid select an alternative animal companion (reducing his effective druid level) and then use Natural Bond to offset that?
8. Does true seeing foil a shadowdancer's Hide in Plain Sight?
9. How does vulnerability to [energy] interact with resistance to [energy]? Apply vulnerability and subtract resistance, or subtract resistance and apply vulnerability?
10. When riding a war-trained mount, do you need to use Handle Animal to direct the mount to attack?
