I was thinking about this Flying MC thing a bit, and I'm going to spitball the options as I see them.
1) Do nothing. Rules are rules, and GW clearly intended the game to support this type of event.
or
2) No flying MCs.
or
3) Flying MCs can assault enemy Flying MCs if both units are in the air. Flying MCs in the air cannot assault ground units, and vice versa.
Um, why is counting FMCs as jump MCs not an option? That seems the simplest thing to me (and probably the best).
I think limiting FMCs to moving like they have jump packs is the easiest and fairest.
I disagree, there are MCs with skyfire for one.
Huh? The only MC with skyfire ability (absent being an FMC), AFAIK are riptides who pay 20 pts for the privilege. In the circumstance in which there are no true Flyers......don't? Just saying. Same with Intercept.
Whats a flying MC going to do? get a vector strike in at unmodified str? more mobility sure, but they need to land if they want to assault anything
Well, Daemon Princes and Tzeentch thingies will have psychic powers up the wazoo, and Hive Tyrants can have what, 12 Twinlinked Str 6 poison shots? That's pretty hellacious. I think the fact they can absolutely choose their battles is more important than anything else.
If FMCs become Jump MCs it puts everyone on a pretty even playing field. I think that's best. Maybe that leaves FMCs paying too many pts for being FMCs? OK, give them -20 pts. Whatever. I dunno. I think it will be fine, unless FMCs are allowed to follow the normal FMC rules, and then the normal MCs will have wing-envy bigtime.
