I use this for fraktal and some fast dungeons where “usual” might stacking isnt that easy and for trashgroups it dosnt matter anyway witch runes you have, you just need 3+ targes in cleave range for easy 25 stacks might on 100 % uptime.
For most bossfights, with dont last longer than 60 sec, i just trow a battle standard for free 10 stacks and fury.
With the 20 % additional boon duration from this food, i give my party around 18-25 might stacks on solo targets, the “free” 40 % magic find boost isn’t that bad too
