I propose to add an additional option to generate a config file per City (https://airvpn.org/generator/) that will connect to the most optimal server for that city based on server load. This would work similar to how when you connect via Country or Continent.
What I mean is when generating config files (https://airvpn.org/generator/) you can only select the specific servers for each city, rather than selecting just the city itself.
The problem with connecting via Country or Continent is it will often connect you to a less than optimal server relative to your location. For example, Chicago based connections might be connected to Florida etc. which ultimately leads to connections with bad latency and lower speeds.
