[2019] The Return of Infected.. with some new ideas during and perhaps after Apocalypse Z

Infected is one of my favorite modes on MP to go on with friends and have fun, but one thing bothers me when it came to the mode.. The lack of classes, sure the classes are "ok" seeing most people (or randoms it's your preference) running Impaler or Scrapper almost always. Occasionally my friends and I talked about on when they return Infected that they should have different class setups each time it's released so us players have a bit of variety. So I wanted to say my opinion with the upcoming Contraband: Apocalypse Z and hopefully the developers of Infected read this but what do you guys think? Should there be different class setups for each time Infected returns, to give it a little spice now and then?
