Am i understand right, that blue dazzled state prevents red dazzled state to be placed? similar with other states (except poison)?
When a blue dazzled state is in effect and the same effect is applied again to the character then the blue state gets flipped to red. So in your example, if a character who has a dazzled marker in the blue state is dazzled again the blue marker is flipped to the red side. You can't have more than one marker of a state on a character at any time with the exception of Poison which specifically says that multiple markers can be applied
Yep Hexers and Gata are both non offence characters so they need some ways to hold their own against the big damage dealers like Wild Bill and Lunah
There are large difference between ways to hold and complete disabling.Through my games hexer and gata very reliable disabling 2-3 enemy characters allowing their team damage dealers to massacre enemy.
