Magma cubes should be easier

Magma cubes are impossibly impossible to kill and even just running past one is too hard. Especially in early game at the nether. They are mostly just to many of them it seams like you need full diamond armor to take them on. And considering that many people will venture into the neather to get a dried ghast it seams that it is to hard. It also is a mean of transportation so many will have diamond armor to get because of the gazillions of magma cubes so they will already have an Eleytra so it renders the happy ghast useless.
