Here's another idea that incentivizes you to focus on learning one thing at a time: it is cheaper to continue to study whatever you are already focused on. If the last thing I added a point to was scoundrel, I can continue to add to scoundrel for only one point, but it costs 2 points to start studying something else. Maybe after you hit level 3 on something, you can switch your focus to it for free. An example:
-Start with scoundrel 1, dual-wield 1. Current focus is either scoundrel or dual-wield.
-Scoundrel 2, dual-wield 1. This costs 1 point. Current focus is scoundrel.
-Scoundrel 3, dual-wield 1. This costs 1 point. Current focus is scoundrel.
-Scoundrel 3, dual-wield 1, pyro 1. This costs 2 points for switching focus. Current focus is pyro.
-Scoundrel 3, dual-wield 1, pyro 2. This costs 1 point. Current focus is pyro.
-Scoundrel 3, dual-wield 2, pyro 2. This costs 2 points for switching focus. Current focus is dual-wield.
-Scoundrel 4, dual-wield 2, pyro 2. This costs 1 point because you are switching to something you have 3+ expertise in. Current focus is scoundrel.
