Original difficulty!!!

The installed Echo buffs is mainly for people who wish to finish the content that they're stuck on so that they can advanced to the next content in the chain. The Echo is not really made for people who already played the old content to death and/or already got all the farming done. Besides, no one's really going back to the old content for loot when there's always better loot to be had in current and future content where the Echo buff isn't applied anyway.

I agree, but I think it's mostly to make things easier for the new players to catch up and not have an eternal disadvantage.

The new content is made for a slow progress so people don't obtain and do everything before new content is ready, and the older content is easier so that new players can catch up.

Roulettes are also there to help new players to level quicker.

The relic quest used to take several weeks, upgrading to Zenith at least 2 weeks, etc. Now you can do the relic and upgrade to Zenith much quicker. Obtaining gear up to ilvl90 is quite quicker now.
