If Haven gets implemented
like it is in MO1 (which seems to be the way SV is planning according to Sebs most recent comments on Discord) I would predict that some players will stay there and play it as the "real" game(just as that was happening in MO1). Obviously they will run out of things to do, so they will ask for more things to do. Eventually they will catch SV in a desperate state (in between big patches) and they will do so. Slowly building a server in parallel to the rest of the game. There won´t be one big make or break thread on it either. Why should Haven NOT have sea dew after all? Why should Haven NOT have a bear cave?
Some of the ideas of Haven will also be used as an argument to persuade the devs into implementing the same kind of systems in the main game. If it works for the population in Haven, why shouldn´t it work for Myrland?
A PvP toggle is an obvious one. More bound items. More viable farming inside the guardzone. So basically eroding the risk vs. reward system that makes Mortal work.
Additionally we might see a lot of more gold farmers since Haven will provide them will a zone to use bots in. Depends on how much profit you could make that way.
Last but not least veterans will abuse the system, putting further strain on the economy and making never ending server wars more likely. Which after increasing the population for a short time kill it off in the long run.
If SV moves with this and wastes more time on "carebear" (by which I don´t mean PvE content, but mechanics that compromise open PvP and full loot) things it will eventually lead to those that came for the niche game quitting. I highly doubt that there is a consumer group interested in the hybrid that MO1 has become in the end. The population over the last few years speaks for itself.
So in short MO2 will either become another trammel or die the same slow death as MO1 did by compromising core designs. Mortal Trammel might or might not be successful, but looking at their competition I doubt they can cut it.
There you go. Full to the brim of speculation and assumptions. When MO2 becomes the game it is supposed to be (
@ThaBadMan could post "the vision" again) despite Haven feel free to quote this post and laugh at me.
