What, do you mean the 410 catchup gear from 8.3? So you're wearing items that have, literally, 4 times the stats of what you were expected? I would be concerned if you were not destroying things with that.
Dunno if you played at the start of BFA, before they fixed outdoor mobs scaling to your ilvl (the scaling is still a thing, but it's no longer overzealous). It was absolutely horrible. You were raiding mythic uldir, but pulling more than 2-3 mobs outside was still a gamble (well, for SP it was).
All in all, any automatic scaling, in my opinion, has no place in RPGs. Or MMOs.
