Atm aldmeri in pst is hugely overpopulated , then is eh and last is Dc.
Having played daoc (and knowing that the lead dev here was also in that game which they had an interesting mechanics for balancing the population) i suggest they should do something similar.
For instance DC should get an 20% increase in xp , gold and alliance buffs compare to aldmeri or something along the lines.
I could get a screen and post right now and see how hugely impalance the population is or you can just look it up on twitch. Everything is yellow and playing something else apart aldmeri isnt fun.
Devs need to do something to balance the population before is too late.
