When you assign talents now, you choose a node and confirm the selection before being able to assign next one.
I would like the option to select several nodes and confirm the talents afterwards.
This would make it more convenient for using stored up emblems once you finally level your hero. But it was also offer a small chance to rethink the assignment. Let’s say I assign emblems to the wring branch. I’d like to have the option to change it before I finish buying talents.
