There is nothing weird about double melding tier 4 materia, but it's random with a low success rate and enmity materia tier 4 it's hugely expensive. Not everyone have the resources or the will to try that way. And for god's sake, i already said enmity+ is a percetual gain not linear, after you stacked some you don't need more, much less 150 <_< and many people already said you stack enmity only in slots where hp can't be stacked
If you're so unwilling to listen someone else different from you, i'm done. I've said everything i could say, but i don't see any change
