Every new improvement they introduced us forces players to re grind . 125 or 150 marks is required to upgrade an exotic and you can store max 200. So to upgrade all your exotic arsenal ( weapons only ) i have to grind 4000 Marks. Are they really think the players will not realise these constant pattern changes. Did you guys also noticed that they are going to force us farm the upgrade materials once again just like original game ? Cricible QM doesn't sell Helium Spin metal etc.. anymore. Their method in Crota back fired and they lost a lot of guardians. Hope this will backfire and they will lost a lot of pre orders. So that they will be forced to learn a lesson.
