Revert changes made on Paradise Rush, you just downgraded what the game offered, lowering its quality:

Removing the first objective on paradise rush is a huge L, it was a unique situation making the map stand out and offering more variety to the game
Also reducing defender bounds doesn't sound good, Forefront bounds are already extremely limiting, this just makes the gameplay even more repetitive and predictable.
If you're trying to get closer to a 50/50 winrate ratio on the map is not a good idea, this is not a compatitive game, fun is more important than stats/winrate.
