Leveling; build for survivability?

[Rbstr]

I put a few points into Vit while leveling. In dungeons it shouldn't matter at all but it helps for soloing and FATEs.

I had 10 points into Vit while I was doing the hardmode primals, Titan specifically, then swapped to full mind after I got my relic. You'll have more than enough GC things to buy the thing.

Titan isn't too hard to heal, unless people are bad and getting hit (and, lets face it, you're not going to win then anyway), you just need to make sure you have enough HP to survive the later rounds of stomps.
It saved me some tome grinding prior to relic.
