This are typical numbers I got running shield dok - learning myself and getting idea how that class perform.
Anyway, results below:

After every won or lost scenario there is a bonus on top of made kills and assists incomes, disparity of ratio is quite shocking.
Normally kills or assists give ticks with ratio 5:1 - 10:1, but the bonuses are huge. I see a problem here.
As you can see on right side, normally exp required to lvlup and renown for same rank is around 13:1 - 16:1 ratio, but if u take into account having renown pot and running only scenarios, that leads to overstack ranks and renown ranks lags behind, especially if you cummulate "lost scenarios bonuses" with ratio 68:1.
That leads to a suggestion to tweak ratio of bonus granted for a scenario. I strongly believe while leveling up it harm players in a long run to give them free huge chuncks of exp and little renown, they should have a better chance to maintain healthy career rank : renown rank ratio.
As a result, I never could keep up my renown rank above career rank, I lvled up 1-10 running quests in Orc City and rest are scenarios spam.

Thank you for reading.
