So far with every new MMO launched many players left lotro temporarily and most returned after a few months, but every time we lost some players. Will ESO have the same effect? Who knows, but what I do know is that as of now we already have 30+ making the initial move to ESO . Those 30+ are mainly our experienced creeps and a few freeps. Go figure what good that will bring to lotro's pvp, expect fraid(s) camping Grams eager to hit a lone creep.
Will those 30+ return or keep playing lotro part-time? Most likely some will, but unlike the previous new MMO's the current state of lotro got a lot worse and the incentive to come back is non-existent, we will lose players permanently.
Besides the fact that there is no balance at all between freep and creep classes, there is also the regular urge of freeps to raid up, get all bonuses and stay raided to hunt solo's/small groups and to camp Grams. I often see Faerdo on GLFF asking for more as 'creeps have a raid' and when I log over to creepside I see no craid at all, its just an excuse to make farming as easy and as efficient as possible.
Elle, I do not know if its Faerdo who is multiboxing a warg in dof or just a freaver positioned somewhere else, maybe he is only using intel over Ventrilo/TS/etc. but I do know he's been using that kind of intel as he said that himself a while ago.
