It certainly easier to reach if you hit high ranks before due to higher MMR and bonus stars.
This is good, as it get people back to where they should be faster. This helps keep good and bad players a little more separated. That was the point of the new system.
It’s still a grind for bad or new players and possibly harder depending on bonus stars those players are getting. It’s still quite a grind to reach first time. There are players complaining about MMR rigging who don’t understand MMR systems properly who clearly are finding it more difficult because they are actually facing harder opponents.
Basically if you reached legend regularly in the old system you are meant to reach it easier in this system.
Also remember there a lot of people that have a lot of time on their hands at the moment (lockdowns), causing more people to be playing. More people playing means more stars being added to the system (due to rank floors), meaning bad players are getting higher up, making diamond 5 easier, making D5 to legend (where MMR no longer matters as much) easier for good players to reach legend.
