So, guren feels a bit underwhelming to me, i mean its 800 potency for 50 kenki(16potency per kenki), while shinten is 300 potency for 25 kenki(12 potency per kenki), now obviously guren is a better ability, but honestly its just two thirds of a free shinten every 2 minutes in single target, its not that great, whats the point of this ability? i wouldnt loose almost any dps by just ignoring it would i?
