Huge gap between Java and bedrock combat

I can say that one of the biggest gaps between Java and bedrock is the combat and I can list some. I've gotten the idea about this because I was playing a java and bedrock PVP server w my friend and I am on bedrock and he was on Java and we were on post 1.9 PVP. First of all here are some things that a java player can do.

.Have anything in offhand

.spam throwables and items like end crystals and xp bottles

.hotkey to put items in offhand

.And more...

That putted me at a huge disadvantage because if my totem gets popped I have to go to my inventory to grab another one compared to my friend which could do that with one press of a button. Plus not only my friend could have totems, but also any item in their offhand. I know it could be hard to put these mechanics in for console and mobile but that is the biggest gap between the 2 versions. At least make java for console or mobile by adding support for controllers and touch screen. It just feels like bedrock has been getting thrown around like trash. That's all I wanted to say. Goodbye.
