Sixth tree "Chaos"

Hey guys, I was thinking about a sixth tree, it would be different from all trees in a few respects

the first part is that when picking this tree you would never be able to pick a secondary tree, and that secondary tree would instead be 2 additional Chaos runes

The second part is that you would not get a keystone

So how?

Well now you have six slots,

pick a rune from any other tree of the same tier in the first three slots, your keystone becomes a tier 1 of any tree, your two other slots are an additional tier 2 and tier 3

So you get two tier 1, two tier 2 and two tier 3 runes of any tree, but only one per tier per tree (So no double dipping in precision tier 1 for example)
