Healing all the way, detox horn is way too good(and fast) not to use. I can't even count the amount of times I've been almost instantly healed of poison without having to do anything. More importantly it along with healing horn is the only thing that is gonna save your life on a hunt. Though recently I've subbed in the last two healers for defense to get armor horn since the true healing horn doesn't seem that great.
The rest of them don't have skills good enough for me to want to switch out 3 healers just to get them.
