Updated Combat and Offhand System + Preformance

First, the combat is horrible and I think that's why nobody wants to try bedrock from java. Lets talk about the combat.

Import the Java Combat onto Bedrock: Before you join a world, it should say a popup, (ex: Choose your Combat System: Timed or Spam)

Offhand System: Also, a popup should say; (ex: Would you like to add an offhand system?)

And last, fix the LAG. I think we all know renderdragon isnt helping that much for mobile and console, especially realms. In realms, if you have more than 3 people on, the lag is horrible, change your rendering system and fix the lag for realms and multiplayer.
