Guildwars 2 WvW is a very good comparison to Crowfall. Honestly you couldnt find a better one. Crowfall is basically some kind of improved version of GW2 WvW. GW2 WvW has campaigns as well, also The Elder Scolls Online.
it depends on two major things, how many people you let work for something and how long and how well they want to spend their time during working for it.
The major thing that produces costs in game development are the people, not so much the equipment. Like even two people alone can make an MMO game these days. And through constant delays and not showing any progress in development costs increase.
Developer these days like to enjoy theirselves very much and want all the big money by making a small game that gety hyped through media like youtube and streamers, and so get rich in 2 just years. Thats basically all there is to why people are working in the gaming industry these days. Not to make good games, because they want to make good games, not even to talk about to want to play them theirselves.
I am not trashing anyone. I am just stating facts.
You are new here so i will go easy but this has been persistent for a long time now and the game is meant to soft launch this year either by summer or end of the year, on top of bugs lag makes it much harder to test and gives alot less motivation to play thus why servers sometimes are so dead. It always ends up being the same names who try to test the game every weekend with a few new ones you might see for a short time and no more.
Also damage is way off getting hit really hard by diff classes.
