If I'm reading this right, and as someone who has played games that sync the item levels but not the skills, no thankyou. People with their whole kit will either be way more overpowered than those without, or scaled so that they are either weaker, or at least at the same dps but required to put in way more effort than someone with half the buttons to press. None of those results are that fun, and I'd rather everyone who can participate in a piece of content be allowed to be on the same footing as everyone else (minor differences in gear being the exception).
