Would it really?
RT shares 98% of the game mechanics with standard Renewal servers. At most what you actually need to do is add an "RT note" on that page when there's divergences between servers. Say the exp page wich explains the exp penalty and it's 15 level range. You just need to add the RT counterpart to that page with the 30 lvls range. Don't need to make an entirely new wiki.
You can also add an "RT section" wich compiles links to all the RT exclusive minutiae, wich aren't a lot.
I'll give you that RT doesn't have a proper database when it comes to monster spawn/drops, but that's just a dedicated side portion of the wiki, not all of it.
Sorry but it sounds a lot like the make up of excuses now that you've been put up on the spot that you could assist the cause, instead of pointing fingers.
In regards to database, the initial groundwork for differentiating servers actually was laid/planned out. When I was restructuring the table design, I had to account for ReStart. So if we ever get someone to help on the front-end stuff to get that moving again, we can hopefully easily roll out for new servers like Poring.
And even then, we can probably think ahead and have a way to show differences for RO:T vs Renewal.
For the actual Wiki, this is something that can easily be done but nobody bothers. Even @Yama over there yells at me to update stuff in Discord. Usually I will mention it to the Discord group for editors and hope that they do it. @Yongky and another usually focus on mechanics, whereas I like to add quests. But as @Ash said, most of the actual content just needs very minor notes. And even for things like builds, it can probably just update the class pages since current builds are listed on the 3rd job pages.
And @MegaEdge, how have I not seen you? I thought you were in our Clandestined Society veterans discord...
