After the addition of the frozen and deep frozen biomes containing the icebergs, the other biomes are being a bit messed up. The lukewarm, deep lukewarm and warm oceans have been changed to a normal just : Ocean; Making them so rare it is almost impossible to find n any survival world.
(As an example, I used a few of the seeds I found to be good in a snapshot before this one and recreated the world in the newest version of the game to test it out)

As the result of this, the coral, coral blocks and fans, also sea pickles are way to hard to find too.

I think we should if we can fix this issue replacing part of the generation of normal ocean to warm and lukewarm ocean.

Of course this is not an obligation, but just reading the word warm ocean in the f3 screen makes me feel I'm at the beach (XD), and also it would make decoration blocks more easy to find and put in our houses, to, you know, make it look more colourful.

As in my opinion, if the new blocks are so hard to find, than less people are going to experience of example having them in the inventory, or able to farm them, making them almost useless.

Hoping Mojang see this and may try to fix this, issue/problem

Thanks for taking your time reading.
