Mettle and relic balance adjustments post Zadnor

[Darkshuda]

I have finished the last steps for a first relic, and went back in Bozja, Castrum and Delubrum, and some things need to be reviewed.
I'm gonna start with the mettle rewards.
Due to the new content and the increase in ranks, the mettle rewards in Zadnor are exceedingly higher than they were in Bozja, we're at 600k+ rewards for CEs at rank 25, and 3.3M for Dalriada. However the rewards in Bozja, Castrum and DR have barely been increased. CEs rewards (around 19000) don't even cover a death penalty (61300). Castrum gives a bit more than before (195k), DR gives 600k which is a CE in Zadnor for close to 10 times the run time in a baseline DF party.
Most of this is due to the algorithm for rewards in previous zones which induces a flat increase as your rank goes up, but the step up in rewards in Zadnor is so big that it broke the algo in previous zones, and do not help motivating players to go back to previous content if you're hoping to get the 600M mettle necessary for a full set of ray buffs.

The relic balance has already been mentionned in another post, so I'll just add that since for the last step the option to run lvl 70 dungeons was added, why not let timesworn artifacts drop in synched lvl60 dungeons, after at least raising the drop rate in Potd. Because this step is gonna be a real bottleneck, and I for one haven't finished my first relic to keep the Irrestible quest active to not miss out on raw emotions while doing Dalriada runs.
