You and your users are appearing more and more clearly to be on completely different wavelengths. New more expensive DCs are *not* what folks want.
And given that the TW gauntlet is in the midst of collapse due to top-guilds having built their own 'test' version of the game, you may start losing whales farming DCs as intently, soon, too. If TW and GAC are hopeless, because a gauntlet opponent can always perfectly counter you (regardless of DC/FDC), then there's no point to spending on DCs.
Maybe the next road ahead has you address these concerns, but I doubt it, as much as I'd love to be proven wrong here.
Edited to add: I did miss the bit about being unable to dust these. IF that means that these are semi-permanent datacrons - more akin to 'squad mods', if you will, that never dust - then a *lot* of my concerns will be downplayed (though still not the biggest fan of DCs). Can we have clarity on that point?
