Thank you for the suggestion!
If i remember correctly we specifically removed the mentioned map as we deemed it to be human sided way too much, instead if it we have introduced new/old maps that players seem to like.
As for "ground parachute" i'm not sure what you mean by this. If you are refering to people bhopping with a parachute it's quite simple to do! As you strafe and reach the apex of your jump you simply hold your parachute key. As you're falling down you release the parachute key. Tho bunnyhopping with this method can be inconsistent.
