i know that pyro wants things kept in his post, but i don't want this being lost in a huge number of complaints...
i think the idea, in concept is great, but there are a few changes i'd make to improve it, otherwise i can see this splitting the community.
what i'd suggest is that HTC gets rid of one of the late war arenas, it's a bit of a waste of space IMHO. second, i think it might be a much better idea to enable all planes in the late war MA, so that we can still have it as it was, for those resistant to change, while the mid-war contains all planes, apart from the later variants, and then that the early war contains just the early war.
it means that each arena isn't totally different, just that the earlier ones are slightly more limited.
as most people have probably noticed, people are happy in concept, but fear that it's too different to how it was.
just thought i'd drop my thoughts in. it's a great idea, but limiting the planeset so much is already irritating people, which, while inevitable, is still not a good sign...
