if you roll on a seasonal server you should 100% understand that everything will eventually wipe. making forever servers for this type of server is pretty redundant, if you ask me.
as for the new vs fresh stuff, from what i have read people asking for “new” servers are those who want brand new servers running tbc to launch alongside the release of tbc classic. everybody will start at 1, and move onto outland at 58/60.
those asking for “fresh” servers are people who just want classic again. that simple. as for the end of those servers, they don’t know. however, those asking for fresh just haven’t yet been told how good of an idea seasonal servers are for classic.
i just want seasonal, i could play classic forever.
