I’d say this ties more into the fact that Tree is very creative about the silver sinks. The issue more or less though is that there is only one efficient way to make silver now, and when you consider how big the silver sinks have gotten, you realize that you are almost forced to do the daily chores to keep up. In some ways that is more like other MMOs, but very little here promotes inflation now that most of the dirty silver and bots are gone.
My recommendation would first be to not sort the CM cubes by level brackets of 100, but closer in range to the gear level. For example, CMs on maps from level 279 (Inner 8) through 327 (Mishekan) should drop rank 8 (gear level 315) materials, maps from 327 (Zeteor) through 357 (Narvas) should drop rank 9 (gear level 350) materials, and then CMs on maps from level 362 (Barynwell) through 387 (Spelltome) should drop rank 10 (gear level 380) materials.
This includes appropriate ore levels, and also, particularly now, higher drop rates on items which are materials for creating raid portal stones. The reason for this is that the raid portal stone gap–even though they come so easily from Velcoffer–makes it very difficult for new players to even get the gear to feel comfortable enough to do Velco. It’s kind of backwards right now.
More importantly though, the stage 6-7 cubes need to be far more rewarding–and should not even have the same loot table as the stages 1-5.
I would really only call Saalus and 330 raids “Daily Content.” CMs to a point, but the bigger issue there is that HG and other “options” for making silver and farming aren’t as viable. The deflation in the post-bot/RMT Tree is extreme enough where selling primuses and HG drops are just not viable, both because of the prices but also that the rarer, high value items such as albums are just too rare, and the equipment drop rate (primuses in particular) cannot compete with CMs. This will also continue to be the case as the advent of new materials will be used in the new weapon recipes, and HG will get pushed further behind.
