One additional per-character Atlas Tree

It would be really great, in addition to the current shared atlas trees, we had one non-shared, per-character Atlas Tree.

If you need one tree to efficiently generate maps, one tree to efficiently generate scarabs, then it leaves you only one tree for a shared mechanic. The problem is that not all character builds can handle the same league mechanic well. It's not fun having to change the tree for different characters, when I find myself using certain characters for certain mechanics. The third shared tree is nice when it is a common league mechanic that all characters can utilize. It just gets boring doing the same thing or having to swap it around and then swap it back.

My suggestion is to add one non-shared Atlas Tree per character. This encourages leveling additional characters, rather than discourages it.

It seems like this would be particularly necessary for SSF and is a reason I haven't decided to pursue SSF.

+1. Argued this for mercs as well. It doesnt even have to be additional. Make 2 account bound, 1 character bound.

Perhaps, but you'll have to pay for it like a stash tab
