I was thinking since the Screamers slash attacks have been expanded to the hexwraths (or something very similiar) do you think its likely that more units will be given similiar rules. There are after ak certain units that seems far more likely to do a fly by attack than actually get stuck in close combat. Great eagles for an example. (and griffons but if they were going to do that they'd have done it with the imperial griffon) ofcourse not all fliers should be able to do his a cyrocopter for an example doesnt really work that way.
So what do you think, which units could be given this rule, is it likely that any more units will be given it?
