Second Wind Rk. II  

While this Disc is very nice for warriors, rogues and zerkers, it is just a waste of a possible usefull disc for monks. Second Wind shares a reuse timer with Moment of Calm which monks get at lvl 75 and is much easier to get even.
Second Wind Rk.2 regens 3000 end over 2 minutes for the cost of 200 end initially and 1 end per second. Regening 2780 net endurance every 36 minutes is a great thing for war, rog, ber but for monk it will almost never get used. Moment of Calm Rk. 2 returns 3750 endurance for the cost of 1 end initially for 3749 net endurance with a 20 minute reuse timer.
The only time I can see a monk using Second Wind instead of Moment of Calm is if they aren't gonna be able to sit still for 2 ticks in the next 20-30 minutes -- in otherwords never... Using Moment of Calm and sacrificing those 12 seconds returns more than double the endurance of using Second Wind. Broken down per tick using Moment of Calm Rk 2 returns about 18.7 endurance a tick (averaged out over it's 20 min reuse timer) and Second Wind Rk 2 only returns about 7.7 endurance a tick (averaged out over it's 36 min reuse timer).

Awesome disc for the other 3 classes that got it, all but useless for monks. For those reading this and getting ready to flame on... just think how you would feel if your lvl 72 TBS spell / disc was only a watered down version of a lvl 75 TSS spell / disc you already have AND couldn't be used if you used the better lvl 75 version....

Monks, save your currency and forget this disc even exists.
