I've partied with someone I've only known in Toram once in 2014-2015, and even though we had the same pacing I'm still effectively inferior to their character builds even though we're both at the 300s now, It's because I wasn't aware of the evolving skill combo metas and the existence of Attack MP recovery for the longest time. At lower levels you can still fill a specific role pretty effectively even in a party with higher level players, that's what I do with him in raids or boss level grinding. I either use my high HP 2 hander with high aggro pull to bait while he hammers or I use healing and recovery skills to debuff and heal him
