I'm not a huge fan of this idea. I don't like being restricted in taking or gathering materials based on level. I think the leveling in Ark fine. Not great but fine. My biggest beef is just the patches of levels that have almost no engrams or no useful/entertaining ones. There just needs to be more stuff in some of those areas to look forward to. Like different bullet types, more weapons both melee and ranged, some different types of transportation items. Like boat types. Either larger boats or smaller faster ones. Just some variety. Skis for snow biomes would be cool. There just needs to be more engrams that are useful or fun.
