Blitz maps should be reworked to not require sitting
Requiring sitting is outdated game design. I can't think of any other successful game that does it. The vast majority of players don't enjoy it, and people have told me they stopped doing blitz just because they play a spec that has to sit.
My idea: make active capture points rotate. Original blitz Eye of the Storm had the right idea, except for some reason Blizzard linked the nodes rotating to the flag capture, which was dumb. Just make the points rotate on a timer that activates after a capture. In Arathi Basin, for example, the map could rotate between farm and stables being active and lumber mill and mines being active. Blacksmith can stay active the whole time for the freaks who love mid fights.
For Gilneas, maybe rotate between waterworks being active and mine and lighthouse being active. I'm not sure this would be great, but it would be better than requiring sitting.
