Nothing serious, just mucking around, using console commands, and discovering the legendary skill tree change. At first I was immediately just plain "Oh it just resets? That's really lame, no extra bonus?", but after some thought I feel like this is really good especially for those really in depth rp characters I know you all have.

One of my favorite character builds I find on this site was the Fallen Hero. The Imperial soldier who looses his ally in combat and slowly let's his grief consume him. I feel the legendary skill tree change can give him more options to those willing and able to grind him through.

I know I'm going to attempt it with a support/healer character who becomes a necromancer. (Absolute cliche Liliana Vess story line, amirite?)

Are you guys thinking the same? If not what do you think of the skill line change in general?  less
