TR experience progression

So the new streak bonus is great, but... it will not change as much TR grind after level 10.
Look at this chart:

TR is not just more experience than in previous life, each life is even harder to gain than one down.
On low levels its only 25% - 50% more, but last levels is twice as much as in life 1st.
Which is little overload. Sure next life should be harder to max, but how much harder?
For me flat increase of 50% is enought to make difference and have motivacion to visit other quest.
It dont have to be made twice as long.

The bravery bonus while nice do not change much at higher levels, since -50% from 190% is still alot.

I know that Programist love algebraic chains, even if they dont make sense.
(like Energy of the Scholar costing from 1 to 4 ap even if its still only 30sp)
But maybe at some point we can stop the progression.

My suggestion:
1st TR,
The cost per rank increase by 5% as it does now, but only till level 10. Then its stops, and its flat. Every rank after lv 10 will just cost 50% more than on 1st life.

2nd TR
The cost per rank increase by 10% as it does now, but only till level 10. Then its stops, and its flat. Every rank after lv 10 will just cost 100% more than on 1st life.
