is the 2T13 alsways better thent the 4T12?
i made some quick calcs and imho the 2t13 is always better then the 4t12.
since you should be able to get 2 "free" heals when you use DF once, it should beat the heal from the 4t12 in any case.
on hagar(10man normal) where i use DL/FL quite often the 4t12 healed for around 100k. so when you use DF two (fight lastet around 8mins) times you should get at least 4 "free" heals (since DL and FL have nearly the same manacosts, and when using DF you should need it so no use for HL). so you can choose where to spend those heals. lets say i choose DL the heal should be equal to the heal done by the 4t12.
since on every other encounter i dont use the direct heals this often(yet), the value of the 4t12 heal goes down. and because of the better use of HR because of the group stacking using the "free" heals on the group beats the 4t12 by miles imho. what do you think?
On Morchok hm last night the 4t12 only made 1,3% of my heal but he healed for 78252 because i had to use DL an FL quite often to top some players. 6min max. fight time so you can use DF twice -> 4 free heals, lets say every HR heals for only 50k thats a total of 200k vs. 80k. clear choise imho
