Grobbulus went from 50/50 with a thriving RP community and good natured war/pvp between the factions.
Then we got about 20 new alliance guild transfers, no Horde guilds, at least none of any note. We now sit at 60/40 A/H and these new Alliance guilds are super toxic, not only to the Horde but they also have been crashing Alliance rp events.
Its pretty demoralizing to be honest.
