All I learned from the new series, is that anyone can pick up a light saber and be able to beat or check "supposed" strong characters.
I also learned that you can warp to any location in the galaxy in sections, making forward bases and outposts meaningless, along with spreading your forces for power projection a thing of the pass.
I learned that even small ships and fighters have the ability to warp around all over the place without the help of a mothership, carrier.
I learned that there is no fucking need for super Dreadnoughts and their like, since they can be easily taken out by lightspeed ships 1/100 of their size. What's the point when you can just drone strike entire fleets which take decades to build.
