This comment from Medjed says it all,

“Currently, we have no plans on releasing new classes, maps, or brand new features for the game. Our future goals are to sustain for the long term .....“

Sustain for what? The only benefit that comes from keeping the game status quo is profit. This does absolutely nothing for your customers. Expecting players to be constantly playing a stale game is unrealistic.

It your goal was to reduce your player base, then job well done.

Why would new players want to join a game that hasn’t changed for 3 years and never will.
