Green Greens is a bad stage for MK imo
* Bomb blocks hitbox is only out for one frame, air dodging as you jump over the blocks is enough so that you don't get hit by them for most characters. Some might have to... air dodge twice.
* If you assume the apples will explode, then they won't do anything to hinder you, and the opponent is taking a risk if he tries to pick them up. The apples are pretty stupid.
* This stage is bad for MK simply because he doesn't have any consistant Upwards kill moves (UpB works SOME TIMES, Utilt is his most reliable upwards kill move and it isn't incredibly strong) He dies upwards easy. He can use UpB next to the bombs and not get hit due to his invincibility, however once he uses this tactic, the bombs take some time to come back, so it is not a permanent obstacle, and like i said airdodging over the blocks as he tries to do this will beat this. It is also a bad stage for gimping seeing as so much of the blast zone is taken up by the actual stage, so this also limits MK a bit more.
Japes should also be legal, to reply to your points specificly
* Camping is difficult to deal with on this stage, it's true. But it is helpful that stage control on this stage is also especially good to have, and if someone is camping but you have stage control in the middle, if you have % lead, then this is a better position, although I'm not sure about Snake or Pit, who can control their projectiles well.
* The klaptraps are very easy to avoid due to the times they come. You can only be hit into them if you are getting spiked or stuffing around in that area already. If you are above the side platforms and are spiked into the platform and cannot DI onto the centre of the platform, then I'd assume you are already on a high %. I don't know if there are any spikes that are hard to DI at low %'s though.
* This stage is bad for MK cause it is another stage where gimping means less due to the stage structure, stage is so big, and the water kills you anyway. However it is good for MK due to high ceiling. It is debatable whether it is good or bad, It's just MU in the end.

* This stage adds to the metagame in some way, in that it doesn't benefit specific groups of characters (although multiple jumps/good recovery/air mobility characters all seem to like it here) but also a bunch of random characters for some reason or another. This stage can be used by MOST characters in some of there MU's. This stage is detrimental in that characters like Link could be CP'd here by anyone, simply coz of how bad this stage is for Link, not because of how it benefits the opponent. I am not a fan of CP's that allow this so heavily, but that doesn't matter.
* It's not so much that "because US do it we should" but that the main tourney scene aside from ourselves is America, and if all of them have it legal then perhaps they have reason for this, and it may be that the majority thinks this stage should be legal, for some reason or another. I do not know if Europe or Japan have this stage on at most tournaments.
Green Greens is a fantastic stage imo, I believe we should have it back.
Japes and RC are good too.
Norfair should also be brought back... I mean you can't camp amazingly on it with Falco and stuff, and you'll find that most characters can deal with MK planking on the sides in some way. And I'm pretty sure the "advanced MK planking tricks on Norfair" are all ******** anyway. It's just the 3 ledges per side that affects anything. The lava is also pretty piss easy to dodge unless you are thrown into it (like the spikes and bulllets on pictochat but thats legal) the wave of lava can be spot dodged you dont need to go in the capsule and the wall of lava halves the stage for a short time. The only true problem with this stage is when there is only one platform due to the wall of lava + the lava going really high so thats pretty silly. That happens like 1 in 4 matches though. I see no other reasons apart from that why it would be considered a bad stage its so geeeewd and LEGAL and LEGIT.

As Gary said, stage diversity alone is reason enough to have most of these stages that arent OBVIOUSLY ******** (like the Mario Bros. stage). As long as they follow the common structure of "ledges on left and right" and "main stage is a simple series of platforms (not hyrule or newporkcity)" then there is no reason to get rid of the stage unless there is some random gimick that makes it redundant (Warioware... although whether thats illegal is still debatable too really... the main stage is fine... but the invincibility power up is gay!).
It gives individual characters a larger array of CP's, and characters that are similair in CP's start to drift apart too when we add more stages, which I think is a good thing. All I ever practice these days are Castle Siege, Delphino and Neutrals... I should practice on Frigate.
PS2, Japes, Rainbow Cruise, Green Greens, Port town Aero dive, NORFAIR, More stages I can't think of...
Need more stages
u so boring melbourrneeee
