The invitation system along with the resent Gold rate change, I personally have gained over 200k in less than 2 weeks. I also was grinding character and faction points as well.

I would really like to use my purple tickets.... but it seems the most players already own both campaigns.

Agreed.
I really loved this game, i bought the Alien Myths and the FP later on (stupid i know...). I recommended this game (on steam and personally to my friends). I can even overlook the stupid reward splitting and blueprint gambling.
BUT.... every time i try to play as antagonist this game is just plain frustrating. Im no fan of PvP, how am i supposed to progress when i play like 4-5 h a week?! Against a good raiders team you simply can't stand a chance. And don't tell me the so called "new progression system" changed anything! I just want to craft some weapons.

Maybe i'll give them one more chance (until Hades Betrayal release). This game need to be fixed, the core gameplay is fine, but there are so many problems: progression, matchmaking, insane prices, grind, reward system, queue times, bugs, etc....
There are a lot of great suggestions (and complaints) in this forum and in the steam community, but MercurySteam does not listen! The only good change in the last update was that card locking needs character/faction point instead of gold.
