We can't have more than 20 stinking vehicle..this isn't a lot Badspot (this limits racing servers to only 20 players)
So what? I've never even played a racing game with 20 players till I played Blockland anyways.
We have handicapped vehicle and sometimes brick physics, baseplates/bricks stay floating in the air after the rest of the bricks supporting them have been fakekilled/blown up.
That's not an engine limitation. This can be fixed with mere scripts.
As for vehicle physics...hell...everyone knows whats wrong with this, there's no point in trying to fortify your base/fort from incoming attackers because guess what, they can just a drive a car through it, nifty isnt it? You can also fly off into space like Team Rocket simply by hitting a brick a certain way.
As far as I'm aware Badspot looked into this problem.
We have probably the slowest moving projectiles in the entire gaming world, so much for making a fast paced FPS server when the game can't even keep up with your sensitivity or high DPI
A majority of the gaming world uses raycasts, which are also available to us.
(this one is a shocker) We have a static shape limit too, apparently I can't add more than 6 static shapes in my elevator (Xalo's Elevator addon, is this a limit he set?)
It's a limit he set. If you look at MarbleMan's castle defense, that's made with only static shapes. JVS also uses static shapes.
Im not really sure about this one either but I remember a while ago there was some kind of limit that explosions could not be spawned on multiplayer servers or if they can there is a very limited amount as to how many can be (is this why the C4 uses the rocket launcher projectile rather than an actual explosion?)
Not sure what you're even talking about here.
]We have a Datablock limit (werent expecting this one were you?) You can reach the limit just by downloading the T+T Pack, Frog's Weaponry and then maybe a couple more add-ons or Music files.
That's an overexaggeration. We can have over 4000 datablocks and the default files barely break 1000, if even passing 300. You're obviously enabling more than just two weapon packs, and while we're on that subject, why are you enabling multiple weapon packs? Are you trying to make an incredibly imbalanced server? Any sensible server host forgets there even is a datablock limit because they only enable what they need.
And you didn't even touch up on the more important limits, like object count, packet rate, and float lengths.
