I`m doing playoffs using all the teams too,....for the strategy sliders I think I`ve got all the sliders set at 3 and I`m getting great results.
The only thing I have to do is make sure that when I get a lead that I don`t let my coach keep me in defend lead,....I prefer to run in a conservative breakout when defending a lead,except for maybe the last few minutes of a game I might go into it if desired.
I don`t mind letting the "coach" do some of the strategy changes,..as I`m playing and changing lines,and faceoff alignments,and making strategy adjustments too,.....but it`s a chore to make every one,and even more so when you`re doing it on the fly.
The cpu won`t pull the goalies until there is 30 seconds on the clock,....it should be doing it between a minute and a minute and a half left at least....so that will be something to check with NHL13 or to give the devs a heads up.
