I just got the Flex version of this trinket, and upgraded it twice, so now it says 37% cooldown reduction.
I wanted to check how it is supposed to work. Beastial Wrath is a 1 minute cooldown (60 seconds). 37% of 60 seconds is 22 seconds. Shouldn't BW have a 38 second cooldown now? With the trinket equipped, BW only goes down to a 43.8 second cooldown. I have tested it and it is a full 43.8 seconds.
Am I missing something? All this is PVE, as well, so it's not been toned down because of PVP, in this case.
Basically what Supakaiser said. If it still does not make sense, the way I get it to make sense in my head is that normally when one second passes one second of the cooldown disapears. But with the trinket for every one second 1.37 seconds of the cooldown dissapears.
i just realised that the tooltip in the german client is translated wrong. I have assurance wf 2/2. With this formular (180/(1+0.45)) for rapidfire brings me to 124.1 seconds and not 127 (ingame) perhaps there are some ,xx spaces in the formular of Scaling-per-Itemlevel that we dont know
