Given the recent influx of new players...
Devs should implement a AFK -> Log Out system.
For those who dont know, when a new expansion is released a similar feature is enabled to avoid server congestion. What it means is that the moment your character hits the 30-minute inactive status, the system automatically logs you out.
While it is a less-than-ideal solution, it should help with the current situation veterans and new players alike are facing. Even if the number of players afk in servers amount only to a couple of hundreds (check Limsa, Eulmore and Gangos just to have an idea), forcing them to exit the game - and therefore stoping loading all the data associated with said characters, from retainers to gear for instance - would lessen the burden some servers are having and reduce the queue even if by a small margin.
Again, this is not the best solution. Better/ More servers are the solution. But unfortunately it wont happen overnight. The AFK -> Log Out system can.
