Rank the Ability potential of Nebulite

for weapon.
1. boss damage
2. % def ignore.
3. % crits.
4. %matt/%att;
5. %total damage.
6. %stats.

what is the most useful one other than boss damage for nebulite atm?
sometime I feel like %matt or %att is better than def ignore, which a lot of people argue it is better.
also, with me having 51% crits, having more crits will certainly help. it increases damage 146% for each critical.
so hard to decide.

boss
ignore
totaldmg/attk
dunno

that's pretty much how i see them

Take whatever is best for Potential and apply it to Nebulites.

All the Nebulite system is, is a "Gem Socket" version of the "Potential Line" we have today...
