And the other side of the argument is that Dominated is supposed to represent the ability of a creature to control the actions of someone else. Whether it's a Beholder's eye ray or a Mind Flayers psionic control or the classic vampire's gaze, it's about the monster getting into your head and making you do something. Therefore, things like allies/enemies should be fudged for the spirit of the power and the monsters using them. This is something that is not RAW, but something that I feel a DM should do. That's my opinion on it and how I'm going to run it in my games.It's not a matter of moving goal posts at all. The goal posts have have never changed:
Ally is a defined rules term.
Enemy is a defined rules term.
Creature is a defined rules term.
How powers interact with regards to targetting allies, enemies, and creatures are defined rules.
Dominated is a defined rules term.
Dominated not switching ally nor enemy, nor how they interract with targetting is an explicitly defined rule.
All of these rules are explicitly defined. The onus is therefore on you to find a rule which counteracts that, something you have yet to do. You have not fulfilled the burden of proof necessary to even suggest the rules intend for ally and enemy to switch!
You're trying to make a case that is diametrically opposed to the explicit text of a game rule... that's going to be an uphill battle, and complaining that 'we're moving the goal posts' is wrong... we're playing fair, it's your position that's problematic.
The sneak attack thing has been resolved. Sneak attack can apply, but combat advantage is hard to get when dominated (not even taking into account the ally/enemy thing because Dazed is part of the Dominated condition which means you can't flank).
