Botanist / Miner: Bugged chronology?

[LuSnow]

Hello All

This time I don't have any problems (can you believe it?), I would just like to understand something.

As recommended in the other thread, I did level up botanist and miner to 60. Once done, it did unlock a sequence of several quests for each discipline. I did them all and had a surprise: the gears/tools of the rewards are of a much lower level than 60! Only the very last one give us one piece of level 55 gear.

How strange... To unlock those quests, we're required to level up to 60, but the rewards we get are for lower levels?

I mean, it's no worries but where is the logic?
