Are there any plans to make DoL less half-assed?

Recently I've been working on miner and botanist, and I must say...

it feels like incomplete classes.

At level 38 you have all skills and you are able to mine all nodes.

From level 39 to level 50 there is nothing. 11 levels of nothing.

By level 3 you literally have all your player triggered skills (stealth is level 8, if you want to count that too).

The only reason to level after 38 is higher stats and to equip the achivement obtained tools.
There's no advance in how these classes are played either. You have these three very basic skills when you begin and you get higher numbered versions of them as you go up. Nothing new. No change in the game play.

The only somewhat different thing you get are these passive skills that are triggered at random and automatically enhance your results in different ways.
