Ran into a kooky situation in our RtL campaign last night. Got the overland encounter with Manitcores and the map was one that had lots of trees. We quickly realized that the OL could park the three manticores on top of tree squares, blocking the paths to the exits and the players could never get past. The reason is trees give units in the trees Shadowcloak, meaning they must be attacked from adjacent squares, but Soaring makes it so that the range is always true range + 4 therefore the Shadowcloaked Manticores could never be attacked by any character. This was further exasperated by the fact that the Manticores get two yellows and blue giving them plenty of range to pick off the heroes from height.
We found this something of a flaw as it forces the game into a situation where the OL is waiting for the players and the players are waiting for the OL (to leave the trees). The only solution we could see would be for one of the heroes to have had Acrobatics and sprint for the exit while the rest sacrificed themselves to the Manitcores to end the encounter. We thought this was pretty dumb. (Another dumb thing is that a large monster has to only be in one tree space to get the Shadowcloak ability...we removed that stipulation and that is how we got around the problem...but as written the problem exists).
I'm interested to hear what the rest of you have to say about this issue.
