Unless you're doing something like AQ5 where the boss WILL smite you unless you can block all damage or something, you need HP...
Even then in AQ5, there's still the midboss that depending on the day, can nuke you damn hard or even nuke you often (in the case of the light one with that trigger). I'm sure some of you are either saving to full burst the boss, or you're like me where you can refill it cause you aren't one shotting 5 mil HP yet
More HP means you can survive more often, and it's even more valuable in the weaker content where you're less likely to deal with "triggers". Hell, it's the one reason why I can sometimes solo wind catastrophe with my fire team, but can always solo it with light, cause you need both the damage output, but also need to be able to take getting slapped multiple times by that boss
But come dual/tri effect weapons, be as picky as you want. I chose to have a grid with about 18 effects, which is nearly doubling HP while acting like I have 10 SR assault weapons (and also nearly acting like my barong is Managarmr without the sub slots).
To each their own in the harder content, but the basics is to make the most of both your HP and damage output, cause we can't all go glass cannon (which is essentially what fire, thunder, and maybe wind is great at... depending on if you even have the hime for it)
