I'm have the exact same issue, same browser as listed below as well as the latest build for IE9.
If I was a player at his table and he continued with his/her over zealous cannibalism at every possible opportunity. I would simply RP my way out assisting him.
My character would simple state, "Your behavior goes against my beliefs. I will not help you if this unacceptable behavior continues. I'm neither an Orc or familiar with their traditions, and by the looks of it, would have none of it. Furthermore, by the looks on the faces of our associates, they don't seem to approve of your distastefulness."
Then I would follow through on my promise. Granted my main characters are support classes, so I might have a bit more pull.
I would only do this if it was an extreme case. Following the, "don't be a jerk" rule is what I try to do. I general don't care how people play their characters. However if I don't like something, I do let people know.
Half-orcs get bite attacks through feats and traits(Razortusk/Tusked). I also think there is an alternate racial trait called toothy too. If he is willing to bite you, he is probably willing to eat you. Well, that's my opinion anyway. As for it being evil or not, it really depends whose eyes you are looking through. I wouldn't consider it lawful or good, so he couldn't be a paladin.
This works, I see it every month as both my wife and I sign up for spots.
If you can't get a GM for a second table, perhaps you can split them up into 2 groups a morning group and an afternoon group. Of course running two different scenarios. You would have to let them know in advance as well. You'll probably get a couple to carry over or start in the early game too. Giving you nice full tables.
Anyway, I would definitely get a sign-up list going for the reason Drogon stated.
At first look it sounds like it would work and even be legal for use in PFS. However the more I think about, the less I would want to do it. Why?
Well, for one, you are going to paint a target on your character if a GM doesn't like it. Your character is being all flashy and stuff - kill him first.
Secondly, you are going to lose your attack and damage bonus to weapon attacks when you pull out your shield. Doesn't sound bad until all the evildoers realize that you have a nerfed AoO. You are going to get flanked a lot.
Another thing is that putting you shield away will probably provoke an AoO. You will give melee evildoers another chance to hit you, and probably without the shield bonus, this alone makes the shield worse than nothing in your off hand.
Finally, you are going to hear this a lot, "You can perform one or more free actions while taking another action normally. However, there are reasonable limits on what you can really do for free, as decided by the GM." They could manage your free actions. So if you need to say something, drop something, or fall prone, they can simple say that's way too many free actions, can't do it. It seems like a lot of frustration for what it is.
Anyway, on the other hand some GMs might not care. Best thing you can do is talk to the person that's going to run a majority of your games and see if s/he okay with it.
I have always enjoyed faction missions, and it's probably one of the reasons I switched to PFS from another system. I also like helping others complete their faction missions with my bard, Ales. Furthermore, the idea of a "Faction War" is something I would enjoy. However, While I like the idea of competing faction missions, it would be tough to pull off. We have ten factions, and only six, at best, would be represented at the table. It's possible, however unlikely, to never see your competing faction.
Perhaps a fix to that is to add a single all encompassing third faction mission that will make all seated factions compete against each other. For example, the first pathfinder to find the jeweled watchamacallit in the scary place gets the faction mission completed. Or perhaps the first pathfinder to gain the influence of corrupttown's mayor completes the mission. I really haven't given this much thought, and I'm sure there are kinks that would need to be straightened out.
As for rewards for faction missions, I would like to see boons and a an option to receive faction enhanced wayfinder. Also, Have faction war rewards scale based on the total amount of fame you have earned.
There's a lot to cram in to a single session, and I don't want to stray to far away from the scenarios main goals. So far it's a formula that works well and doesn't need to much tweaking. You also have to be careful, because like most things, some people take things far to seriously and feelings get hurt when it comes to competing. So please be mindful when creating these challenges.
