This page: http://mondaynightcombat.wikia.com/wiki/Endorsements Says that bronze/silver/gold gives -25%/-35%/-50% recharge time. This thread: viewtopic.php?f=27&t=8231 Says -20%/-26%/-33.3%. Which is correct?
One may mean rate increase. Calculating the skill regen time by how many more times per minute it can be used. Bronze definitely makes it regen 25% faster, and gold 50% faster.
Gold makes the skill recharge 33.33 percent faster not 50% faster. We had a pretty long discussion about this. All skills have a base recharge of "1" Gold adds .5 making the recharge now have a base of 1.5 The confusion happens when you assume all skills have a base of "0" 0.5 would be 50% faster. However 1.5 is not 50% faster. Example: Base skill recharge timer of 10 seconds so this skills 10 seconds is represented as "1". A gold recharge adds .5, making the skills modified recharge "1.5" 10 / 1.5 = 6.666 so the modified reuse timer is now 6.66 seconds 10 - 6.66 = 3.333 So the Gold endorsement is taking 3.33 seconds off of the base timer of 10. 3.33 seconds x 100 = 333 / 10 = 33.3 So the recharge reduction from a gold endorsement is 33.3% This has been confirmed. To put it simply, the Gold Skill recharge DOES modify the Recharge timer by .5. However all skills carry a base modifier of "1". this is what causes all the confusion. Hope that clears it up for you guys.
This is probably a more accurate way of describing where the confusion takes place. Edited based on \/ though I'm starting to think I may not know what I'm talking about.
I'll leave it to cranck to clear up that part but let it be said that the base recharge is not 1, I worded it wrongly. Regen is a balance factor, regen runs on a timer of 60 to a skill having a regen of 8 recharges in 7.5 units and when you apply gold recharge the regen factor gets adjusted by 0.5 (effectively 1.5) ending up with 5 seconds (8*1.5 = 12, 60/12=5). But the "base regen" is not 1, either I worded it wrongly or he misinterpreted my statement. Cranck's formula using 60/(n+n*bal_end_skill) is a better way to express it (where n is skill_regen)
