I've seen low population is a problem which regards some servers, and a similar thing is on Dune Bantha Eu Pve server. I play imperial and i've never seen more than 18 characters at level 50, with an average of 10, disregarding the time i checked (it can be morning, afternoon evening or night... never seen more than that). on every planet or station the population is not better at any level, cause i think since 20 december till now the max peak was 80-100 player in low zones and now is far far worse than before pheraps because some people decided to stop playing or whatever, i really don't know, but the population doesn't grow in any significant way at all..... and at 50 we are stuck unable to do anything cause there is only one guild with the min numbers to start a raid or instances, and then an absolute void... no instances, no raids, no warzones cause the queue now with only 50 are infinite, daily pvp on Ilum will take about 40min if you are alone to recover the chests and 0 republic to kill, ecc ecc..
we tried to ask if a free transfer to a more populated server is possible to solve the problem but bioware answered that is not available.
I hope they take some kind of countermeasures very very rapidly cause every content they bring to the game is useless if you can't do that just because there isn't enough people to do it. Free transfer, merge of servers ecc. anything but this. Or i think that they will loose several subscriptions, cause the will to re-roll another character from 0 to 50 on another server is quite null.
