I think that a lot of people know that the spawn rate is insane, and it's really annoying when I am building a base and mobs spawn and litterally a 100 zombies are attack me. Also giants are really annoying because you have to wear armor when building a base or you will most likely die. I think surge you should add eternal day or at least decrease the spawn rate.
If you knew how many mobs were spawned.. Also I think it would just be better to fix the solution instead of just having to make someone place torches everywhere, it also might make new players quit from the amount of Giants spawning.
You can set a Mob Spawn limit in the ClearLag config here is the line of code you would need to edit mobegg-limiter: enabled: false check-radius: 8 max-mobs: 5 what the above code means is only 5 Mobs can spawn in a 8 block radius you can also edit how "far" a mob can see thru the config.yml <- Click to view full config files for ClearLag. this will also make it so players cant spawn in tons of mobs with Mob Spawners without killing them first, I hope that helps the lag issue
