Yeah the way its worded is very confusing. When you wanna add Q and E to the combo you press the respective key along with the outer/inner combo. So it should look like LLR R+Q or LR L+E. You don't just press the Q or E key to use them. Took me awhile to figure it out.
One of the big changes I noticed after starting s2 was that you go back in time in order to try and change fate. You go to Malina so you are not interfering with everyone in Colhen, trying to change the fate of Tieve and Keaghan. At least a few times I've had NPC's mention Tieve directly, and not have it be this "why does that name sound familiar" dialogue. It seems like in Rise when you start s2 she hasn't become Morrighan yet. Correct me if I'm wrong but that's what I've interpreted so far.
