Same as far as my general resistance to learn a new system, don't want to sound like a cranky dude but they really made some things tougher ...
-baseball betting for example : (haven't figured out the pitchers picks, some game plays yesterday auto selected both pitchers and some plays asked me to choose one, the other, or both pitchers for the game, the old layout had this pretty simply put with check boxes) ,
-haven't really figured out the parlay's and round robins... was really easy with the tabs they had before , now it's all top down / drop down menus, kinda annoying
-and really don't like the layout / scheduling (like for Soccer you used to be able to pick the region/league OR just scroll through the times of games in order of start time for the day, now you can't really do that at all)
Too childish in layout, looks like it's for little kids...
Those are my initial thoughts on it ...
