I can’t comment on item #1, but in TBC it was changed to where you only respawn in the cave if you have no graveyards controlled. I think in Vanilla the game sees the Cave as just another GY, so sends you to the closest one available which causes the issue in your second example.
No. If you are fighting for control of SFGY as alliance, you respawn in aid station. If you are fighting as alliance to defend SPGY and it gets soft capped, you respawn at starting cave.
Yeah I seem to remember a lot of AV fixes in TBC. It’ll be interesting to see what changes make it into classic . I don’t necessarily agree with all the upcoming changes, but it’s good that they are going to try to make it better.
This iteration of AV is complete garbage. Just stop playing it until TBC. Blizz has no interest whatsoever in fixing the blatant Horde advantages they designed into it.
