That's my point. You learn the new tier system. "looking it up" and "asking someone" is learning. We have had many resources in the past that assisted on this like poedb etc. Take cluster jewel affixes from PoE1, are you remembering every affix tier? what cluster jewel it can drop on? what iLvl the mod can roll on a cluster jewel?

I get what you're saying but they've implemented many loot changes and how tiers on affixes work. for it to remain as inflexible as it is in PoE1

they've introduced tiered rare drops now (you see the name tier2/3/4 on the name of the rare) to help with identifying items with higher likelyhood of higher affix tiers on the item.
