This is somewhat dangerous territory though, as it opens up the possibility for veterans to heavily use those tier 1 recipes themselves and push new players out of the market completely. The other way around (tier 1 players delivering materials for higher-tier recipes) are usually more favorable.
Can you maybe elaborate on why you think that “having more of these types of recipes, also at higher tiers” would work against this problem? On first thought it seems like this would just replicate it for the higher tiers as well.
Thanks a lot for the input!
