Here’s a shocking revelation: MMO players do not actually like having all progress reset in the blink of an eye. So you can understand why the latest post about server wipes for The Repopulation treats the topic gently, since there’s no quicker way to anger players than by telling them that everything they’ve worked toward is now gone. Not that it matters too much, as pretty much everything will be reset with the game’s full launch, simply due to the server structure.
As the official post explains, the game may do system-specific wipes, such as resetting all crafting progress, separate from game-wide wipes. Only one such wipe is planned as the game moves closer to launch, but the actual launch server will be separate from the game’s test server (the currently running server), so any progress would be starting fresh regardless. It’s also worth noting that things like backer perks are meant to be tied to accounts rather than characters, so a wipe shouldn’t affect those benefits. Get the full explanation on the official site.
