without it becoming a huge stage debate and BS..
out of stages that have constantly been talked about for a list:
i think cruise, luigi mansion and halberd should be banned.
cruise is past a counter pick for a majority of cast with almost unwinnable situations.. it goes past a 'counter' stage at points. Luigi's mansion as well. While it may help a few characters out, it overwhelmingly helps destroys all form of a normal match. It becomes more about the stage then it is the actual fight of the 2 characters. Stages should give advantages and not halter the match and gameplay. I feel mansion isn't right. Halberd out of the 'moving' stages, isn't terrible but the few obstacles and interferences (regardless of how easy) can make or break a fight. No one would want to trip into a bomb or beam to lose a match that was even prior to the stage (just an example).
With that being said,
i think delfino, frigate orpheon, brinstar , poke 1 are fine.
stadium 1 has always been ok. new windmill is stupid but overall the stage is the same.
SO LONG AS VOLUMES ARE UP on tv's, frigate is fine. If you can't hear the TV it is unfair to play on.
The stage itself is pretty great aside from the alarm noise that you need to hear. Good platforms and spacing.
Brinstar has been ok for a while and should stay ok.
Delfino is the more fair and playable, cruise. It has a few walk off areas but rarely an issue. It has various stage layouts for more variety of play and character selection in terms of a real 'counter' stage.
castle siege I am neutral on but I feel it is playable more so than cruise/mansion.
