Just like you, I don't care much for any of the new content, and Mabi really went off the rails for me starting with G16 at the very latest. That doesn't mean that there aren't some intriguing features in those updates, but the whole feel of the game changed way too much. Many here feel like that, and I assume that's what got many of us here in the first place, the premise of going back to pre dynamic combat, pre power creep, pre reforges, pre raids, pre Shakespeare, you name it.
That being said, from the start one of our main goals with Aura has been to emulate Mabinogi, and that is what we're gonna do. Generation for generation, season for season, we're gonna implement the official content, because that's what emulation is, but I see it more like implementing the building blocks for us to introduce custom content. Us not liking the official Shadow Missions for example shouldn't mean that we won't implement them at all, but that we do implement them, and then everybody can try to improve upon them.
The beauty of Aura is that we can all customize the gameplay to our liking. If someone doesn't like G13+, well, just don't enable G13+. If you want G20, but with the old combat, enable everything up to G20, except for the new combat. You want a world without giants end elves? Just disable G4~8, act like Iria was never discovered. That's the other main goal of Aura, 100% customizability, in the simplest way possible.
I can't tell you what users are gonna do with Aura in the future, but I can guarantee you there will be people who think like you, people who will introduce custom content, rather than update to generation X, people who will modify content we may have not liked on officials, in a way that makes it bearable, or even good, and people who will pick apart the new content, enabling only the good features.
