I'm a new 175 GX and have several nab's cloth to slot with element cards. Having some with a higher FS than others I'd like to put the elements I'd find myself using most for MVP/PvM/Instances/ET in the highest FS Nab's. The problem is I'm unsure what content I'll be tackling most aside from interest in ET. Undead and Shadow seem to be good choices from what I'm read, but I'm unsure outside of those.
If you had to pick at least 3 in order, what would your top element picks be? Thanks!
