1.Personally, imo, there needs to be some sort of daily/weekly reward system in there. This is also something I wish Eureka got, but they did at least put in EXP gain in the Challenge Log for that area. Maybe do something like that for mettle?
2. Rip Castrum out and make it queueable from outside in Gangos like DR is. Only reason is so this can be beatable in the future. I know in the LL they pointed out they know this is a bottleneck, so I'll wait to see what they come up with.
3. Make the essences and lost actions better explained in game and add a reward system (becides the earrings) which rewards for collecting them.
4. Make the drops the same in Bozja as they are outside. (Really I'm tired of running CT raids please.....)
