Yeah I definitely agree, we want everything to be as simple and quick for the end user as possible. Something that came to mind, for instance say you have a certain amount of items in your inventory, a certain set of gear items you want to use for PvE (where you have as much luck in your different items as possible) you should be able to quickly equip it even if it's not literally happening on-chain. It'll be enough that the game and website know you own these items and the game server checks you still own them to let you use them rather than relying on the chain as some other games do that I've noticed. Being able to swap quickly between PvE Luck gear to PvP gear or a more tanky/lasting gear and other combinations should be as easy and quick as possible for the best UX.
A lot of actions we definitely want to keep on the server rather than blast chain transactions constantly cause not everything needs to be verifiable and immutable.
