Top of the Tree: FV215b

Ectar:   Discounts don't stack. 30% is greater than 15% so you get the 30% discount, they don't add up to a 45% discount.  

Ectar:   I guess this answer may get lost in the forums but hopefully people will reference it.   For a little while now there has been a bit of a credit saturation/flood. It's been easier more than ever for players to generate income. High tier tanks especially were becoming credit farming machines and if you were savvy, it was possible for premium tanks to earn even more credits.  At the time no one really complained about this because well, it was a massive return for little effort and players benefited from it.  Everyone did kinda know/accept however it was a bit broken and not how we really wanted the progression system/credit generation system to work. The mission system was new however and we wanted everyone to see how awesome this new feature was.   To give a perfect example of how crazy it could be, in July last year It was possible to have up to 60% credit increase on tier VIII to X tanks from a certain tree by combining weekly/monthly events. 30% increased credits for Big & Heavy - Fv4202 line (event lasted for 2 weeks) 30% increased credits for being in the top 3 damage dealers. (This was either a monthly mission or a weekly mission)   2/7/2013 - 105,788 credits earned  Tank used - FV4202 2/7/2013 - 104,614 credits earned Tank used - FV4202 6/7/2013 - 125,793 credits earned Tank used - FV4202 8/7/2013 - 91,499 credits earned Tank used - FV4202   These matches are not made up. As you can see these examples are clickable links to my own replays. Now I consider myself a decent player but not great and these replays were a snapshot of the kind of credits I was pulling in. An average game rewarded me with about 70,000 to 80,000 credits. I was walked away with about 50k profit after repairs etc.   To cut a long story short, for a little while now it's been too easy to make extra credits on top of how the game was designed with regards to advancement. High tier tanks especially are not intended to give returns better or similar to premium tanks.  High tier tanks are also priced in such a way so that they take longer to get. As there isn't much in the way of credit sinks in the game, the only alternative option *for now* is to tone down the amount of extra credits players can earn on top of normal game play. This credit earning downturn is effect across all regions.   It's likely that credit missions for things like being the top 3 damage will return, but we have to make sure it's not possible to combine them with other missions and again we don't want a scenario where the missions basically circumvent the progression gates we have.
