@Dariush: Yeah, you guys had a weaker power. But you have to look at the overall set-up.
The Werewolves had a basic team kill and one that could be made unblockable. But they also had very little way of getting additional information, since the Warlock has to pry information out of dead people, who are all either 3rd party or on a team, and thus not too likely to give him useful information.
The Templar had a Kill and a Roleblock, but they'd have lost the Kill if the Templar himself had died. They were tough to take out, but only got a little more information than the Werewolves since the clues the Sage gets are pretty cryptic.
The Brotherhood had a stealth kill, which while weaker than a straight kill was also pretty much unblockable. Which is why Toaster died even though he was a Knight. Your Mark could be roleblocked, but the actual Activation of the Wand couldn't be stopped or prevented. You guys also had two ways to get information, one of which was Passive once placed, and the Wizard to let you protect anyone you needed to.
I feel like it was, overall, pretty well balanced. All teams had a decent chance to win up until the end, when everyone else decided to take you guys out instead of going after any other targets.
I was surprised that Tiruin was left alive, though, since he was an unlynchable SK at that point. I figured more people would have tried to kill him.
The Power Boosts boosted someone's abilities. So Org got to talk to ALL dead for a night instead of just one, and Bookthras basically got to use his power on himself. The specifics of what it would have done varies entirely on who gets it.
