Serenity = 4 seconds of immunity, 20 second CD.
In those 20 seconds, the DH can SS like 6 times. 6 x 1.5 = 9
DH dicipline pool = ~40 depending on gear. (default 30, lets say u get 10+ max dicipline from gears)
cost of SS = 14 dicipline.
14dicipline x3= 42, ( 2 will regen in time) you can get 3 SS with full dicipline pool
1.5sec x 3 SS = 4.5
nowhere close to 9 seconds.
oh and did u also know that SS has 3 second cd?
so we get 1.5 seconds of invulnerability, 1.5 seconds of 1 hit death chance and repeat.
the only way we get more consecutive SS is if we use prep and thats on 45 second cd.
learn yo !@#$ first before u call others 'stupid kids' mutha %^-*a
