Also, not to sound like sour grapes, but the reality is that the mats for that vs the superior healing really aren't worth the cost for the 5 extra points of damage.
4x Greater Planar Essence, 4x Primal Life = +10 damage +30 healing
6x Large Prismatic Shard, 6x Primal Fire, 6x Primal Water = +15 damage/healing
On my server the GPE goes for 5-7g and the Life is 15-25g so that's an average cost of around 104g for +10 damage.
On the other hand the shards, fire and water all go for 20-30g or more, but even calling an average price of 25g each (which is cheap really) we're still talking at least 450g for +15 damage.
So what it comes down to is whether or not an extra 5 points of damage is worth 346 gold to you?
When I'd done the math and combined that with the rare drop rate, I decided that no, it was not worth the time and effort to get, much less the cost to get.
