Weekly boost list update

Tiadorus

Add 5* characters to weekly boost list. We have so many 5* right now that are forgotten due to their old mechanics or some other reasons. Adding 5* to the boost list (let's say 2 5*) would fresh up game since people could use their not meta 5* to compete against meta without boost. It shouldn't be God boost as for release characters, bit also more than 14 levels as for non-single character events.
