no it didn't... and no they didn't eliminate a level.
it's been said already, you couldn't have searched for a lvl 1 trainer, just a lvl 2
when you went on find replacements and chose the min or max lvl it would be 2-7
it's still the same now, basic = 2, superior = 5 and world renowned = 7
as it has also already been said, if you hover with your mouse over the "superior", a 5 will show up, same as with player skills.
