Magma cubes have been buffed up to an OP level

Ever since the Nether Update, magma cubes have become OP. Let me give you an example. Magma cubes before the Nether Update were very rare. I could barely find ANY. Now they are EVERYWHERE. I am aware this is already a reported bug, but this is not my point. Magma cubes have gained 3 ridiculously OP traits that now make them INFURIATING to encounter. Here they are:

1. Magma cubes spawning sizes are BROKEN. About 80% of the time, large magma cubes are spawned. The other 20% are small ones. I have barely seen a SINGLE medium sized one. The fact that most are large is annoying enough, but it gets worse, which leads me onto...

2. Magma cubes are rigged when splitting. Every time they split, they should split into either two, three or four new cubes. But they are now stuck on four, meaning that just one huge one is now RIDICULOUSLY powerful, and with the terrible spawning, if you come across even 2 you are dead.

3. Magma cubes can double jump now, meaning they are IMPOSSIBLE to fight!
