"It would have been nice to know the reasons behind that decision...oh well. "
I believe the main reason was the item placement. From the guys I talked to the map was simply unplayable with the original item placement (only 50h on map).
I ran around this new remix version and it definitely seems better. However, it still doesn't seem quite "right" to me. Note that I haven't played this version w/ anybody yet so I'm kinda going on theory here.
-Possibly move MH to where LG is. The current spot just doesn't seem like a place for an item as important as MH and putting it at LG would make for more interesting battles I think (imagine somebody waiting near that doorway and then the other person RJ'ing up to grab MH).
-Move LG... somewhere else.

LG should be far away from RG anyway I believe since you don't want players to control both RG and LG too easily.
-Move RA down to bottom pit area in the corner (opposite from tele). I think this would make more interesting fights for RA since you'd have to drop down into pit to grab RA. Also, if doing that I'd move the teleporter exit obviously so it isn't too easy to escape. Here's one possibility for tele exit: Put at top level in the same room where that lift currently is (and lose the lift), and remove that curved part of walkway where RA currently resides so you have to jump a gap when coming out of tele. This would mean RA is still quite dangerous to get cas you have to drop down to pit and have 2 options: the JP which is death if the other player is in room w/ RG/LG, or the tele which is dangerous because you have to jump over that gap up top and could get air rocketed pretty easily. This would make things a lot more interesting I think.
-If you *don't* decide to change the teleporter location to what I said above, at least change it so you don't face a wall when coming out. It's always annoying to telejump out and run into a wall. Teleporter destinations should almost always point in a pretty open direction.
-Weapon placement could be a bit better for the minor weapons. I'd move GL up to the top floor somewhere (maybe RA room). I'd put SG in a spot where spawns are and it is relatively tight so it really gets used.
-I counted 1x50h, 3 (or 4?)x25h of health on the map. Better than before. Might be enough health but could maybe use 1 or 2 more 25h's, but testing would probably show this.
-Think I remember seeing rail ammo on the map? I don't think you need this since rail is powerful enough as is.
