User blog:Carbonite 0/Resource Cap Enforcement (Sort of) Part 2

"For 3.0 and 3.0 ONLY, the soft cap on Tier 3/4 resources will be 500 and the hard cap will be 1,000. So if you had 2,000 Skulls, the most you will be able to hold is 1,000 once this goes into effect. You will be able to legitimately earn up to 500 of a Tier 3/4 resource at this point in time. To reiterate the situation, we were originally going to clip everything to 2x of the soft cap which would have been 200 for Tier 3/4 resources, but we changed that to 1,000 for those resources. What we are going to do will actually be better for everyone as all of you will be able to earn extra resources during 3.0. We are doing this because the alternative would have been to cut everything to 200."
