I have just been playing Java edition, looking for some parity features that I could possibly suggest, as this website now allows parity requests as well as bug reports. 

The most obvious feature in need of some parity is the Raids.

• Witches should seek other Illagers and heal them with Regeneration and Healing
• Illagers should be able to join a raid or patrol if one is happening nearby (and be counted towards the raid bar)
• Pillagers should use the Multishot enchant on higher difficulties
• Evokers should be able to be Captains
• Captains should appear in the Raids

I hope these can make their way over to bedrock soon

Thanks for reading!
