I am reading EfaE and it states many times that players need to roll for observation checks, one check for each player.
Isn't this overkill? I mean if there are 4 PCs, and the check is easy, is there a reason for all of them to roll? It's nearly impossible to miss. Is any of you using just one player's roll? Which player, the one with the higher characteristic, other things being equal (all PCs are together, all are alert, all are in same proximity to target, etc)?
