I suppose an outside candidate (c) is to continue to do what we did in Red Storm and just work to grow the base of GV players who are fine with that (as they do exist). If there are GV folks who feel that this (c) is better, feel free to say so.
I wouldnt call myself a GV folk (even though I GVed in Red Storm), but I believe (c) to be the best option...simply because I really do not like the idea of the other two.
A Stalin's Fourth type of deal with no designated GV slots would, in my opinion, create GV battles where half the participants either don't want to be there, or have no previous experience in tanks.
A sealed-off ground war would, in my opinion, be a little too gamey, especially given the limited number of ground units we have available for use. Also it would not engender any sense of team unity between GVers and fliers, which I think is great bonding in scenarios.
I don't think the method we used for Red Storm was perfect, but I think it's the best alternative we have, given some modifications.
Here are my ideas for modifications:
1) Spawns that are a little further out, and also with careful attention given to the fact that neither side will be ale to achieve air superiority before the other (no side has airfields significantly closer than the other)
2) Make some of the objectives "non capture" objectives. Base capture has so many problems with "gamey"ness, plus it allows either side to easily funnel air support to an objective that is clearly marked on everyone's map.
What could we do instead? I'd love instead to have some objectives such as defend a railway bridge in some location, defenders set up along a rail line that has an enemy supply train periodically coming by. Each time the train passes, the defenders destroy the train. The attackers must regain control of the railway bridge, and the way to document victory is to have someone on the ground take screenshots of the train now passing undamaged over the bridge. That is the victory condition for that objective.
Not only is this more "realistic", and less incumbered by arcadish game mechanics, but it makes it slightly more difficult for air assets to be vectored in DIRECTLY to the battlefield. Sure, they will find it eventually, and with KP vectoring some will find it easier than others, but that slightly discrepancy between having a large flashing "V23" to be vectored to, and having to find something like 9-8-1-5 might create just enough "fog of war" to eliminate some of the simultaneous air asset overwhelming of ground forces. I think it would make the battle for air superiority over the GV battle a little more dependent on communication and skill, rather than mass numbers. And in the end, if I get bombed in a GV because the other side's air support is better skilled and better communicated, I will have no complaint. (GV's will still be able to take AA units of course).
Just an idea that I think we eliminate some of the complaints from GV'ers (remember you still can't please everyone). But I think there will ultimately be far more complaints if we go with either Options (a) or (b), as you described, Brooke.
As for the idea of eliminating GV's entirely from scenarios, I really hope this never happens. Even in future scenarios if I do not GV, I still greatly enjoy having that aspect of the scenario to "root for" and support either directly or indirectly.
