Personally I think the max cap of 200 crucible and vanguard marks should be overall removed.
It doesnt make sense that only 100 marks can be earned per week AND theres a cap of 200. Anything that is worth buying is about 150 marks.
Solution:
1. Keep 100 marks/week but remove the 200 cap
2. Keep the 200 max cap but remove the weekly cap
It needs some type of balance because the current way it is doesn't make sense.
Let me know if you agree and tell me your suggestions on how you would like it to be change; if you even want it changed.
Hope someone at bungie takes this into consideration.
