Two models (A drom the active player and R from the reactive) are in engaged state. The actove player activates model B close by. (All the skills do not effect R) R declares doge, because he thinks B is in his ZoC. At resolution it is found that B is in ZoC of R. Does R get to disengage from A, if he passes the dodge roll? I could not find anything preventing this...
Yep, Dodging is supposed to be a lot more effective in N4. Remember that an Engaged trooper in CC will be at the - 3 penalty for not having LoF to the Active Trooper.
