In defense, mushroom biomes are lackluster. Giant mushrooms, and fairly useless mooshrooms. Only real benefit is preventing hostile mobs.Quote from KyoShinda
---I can understand the want to add more to ceans, but it still doesn't justify oceans 24-thousand blocks wide (which are found pretty often). I remember the last time I bothered with oceans, I told myself, "YES!! I am determined to find another mushroom biome and drag over some mooshrooms with wheat. Laying back in my chair my mind starting going numb for the 2-some hour journey hitting a mushroom island at 15k then the 3-some hour journey of bringing them back with me (although now we can drag mobs through the portal).
I don't think oceans still being around could be bad, just as long as they were less often.
