so i've fixed up a lot of issues that you mentioned plant. the spawnkilling is almost completely gone. i haven't been mass-spawnkilled at all today. the center point is pretty equally balanced to me. its been shifting quite often and is always the main hotspot on the map.
I'm going to go over the OP points to be clear.
Weapons Imbalance
there is nothing imbalanced at all in a way that would affect gameplay drastically. The RPG and GL both have the same exact radius damage. The bullet weapons are basically only skins of eachother. There is no OP weapon that either team has that causes them to dominate the other. The use of vehicles and turret positions around the map are what gives the teams an advantage. The weapons in the spawn room are not the only weapons on the map. There are other weapons 2 feet away from each of the outposts (which you can teleport to).
Spawncamping
Was a HUGE issue yesterday. I fixed it up today and it has been drastically decreased. The bomber (a mega spawncamping tool) was removed and replaced with bombs. The bases have a bomb shield over the spawn to prevent spawnbombing and rocketing. Killing on spawn island does NOT make it spawnkilling. The island is meant to be under heavy fire since you NEED to capture it to win the game.
Map Setup
The walls I set up really prevent blue from using center point to camp the reds. You exaggerated how easily blue can defend center point. Tanks can easily demolish defenders positioned on the walls. If there was a constant defense, yea, it would be pretty hard to capture. The center point, like I said, is usually always the main hotspot of combat. There will always be people getting blown up there. It's not because of weapon choices or map layout.
