Challenge Log Xp needs a big boost

[Nezerius]

I think the only thing needed is a fix to the scaling of the 50-60 DoW/M challenge logs, as the 1-49 ones are fine.

Currently, the lvl 1-49 rewards scale with the players level:
15% exp reward from: Feeling Lucky (3 dungeons through Duty Roulette), both FATE logs, both levequest logs,
10% exp reward from: Dungeon Master (5 dungeons), You're the Hest Around II (10 guildhests),
5% exp reward from: You're the Hest Around I (3 guildhests)

At 50-51, those suddenly drop to 9.75%, 6.5%, and 3.25%. Past 51, the rewards are the same as the 50-51 ones, and stop scaling with level (84.3k, 56.2k, 28.1k)

The crafting and gathering challenge logs seem to be fine, as those have the same scaling from 1-60. As a sidenote, this also makes the Meld Your Heart (meld 5 materia) challenge log great for leveling, now that it's possible to do melds as a DoW/M, since it'll give 10% of a level, even at lvl 59.

It's already a substantial chunk.

A lvl 59 player will get 2.16% of a level from the DoW/M log with the highest reward, 0.72% from the one with the lowest reward. I wouldn't really call that a substantial chunk.
