I feel you. We were discussing this here as well: Why I love playing on a medium pop PVE realm - and can't.
It feels like Blizzard is only catering to the needs of players on PVP mega realms and destroying our way of playing in the process.
On Lakeshire (German PVE), we have so many players now! All because of free transfers to an already well populated realm. Players from Venoxis PVP and even English PVP realms now basically outnumber others and they brought anonymity, rush mentality and GDKP with them. The realm culture is just different on smaller realms. It is just sad and infuriating.
