So... you solo in blue line or redline, and you group in yellow line...
Fair enough. The problem is that yellow line is a whole different skill set and they skills and responsibilities of the LM in the raid are many. As a tank or healer, you often get a kind of tunnel vision... you have a job. You do the job.
I am returning to my LOTRO after a several year hiatus. My other classes look easy enough, but I look at my LMs yellow line toolbar and despair. He's only level fifty, but three bars are filled with skills, most of which I will never use outside of a group. Any suggestions for skill priority, learning to group effectively at "mid-levels"?
