Not my playstyle but happens alot on the servers you have to admit.(Also happens to be one of the most annoying parts of vsh/ff2)
I can see where you're coming from with it, but keep in mind that the servers get pretty full. Imagine 25-30 people on that map, absolute chaos.
You do make a valid point with the trick-stabbing and such, the jump-pads help the map out a bit for mobility. What it really comes down to with this map is 2 things: it's small, and preference.
Some people may like it, some may not, but I was admin of a server that ran this map with 20-25 people on it at a time, It was so much chaos, many people raging, no-one wanted to be hale because you would just be knocked back into the killzone multiple times and die, or even just as a player, everyone would either fall to their deaths from a misplaced jump or getting stuck on something in the way.
And you can't forget about hale's rage. With the low mobility, if you're caught in that rage you're doomed.
This map in my opinion is a bad fit for a popular server, but that's my opinion.
