Any information about the opponent is welcome. So it would really make me wonder if anybody would answer this question with yes. Imho playing without HUD online is like playing blindfolded live. More so since there are free alternatives to PT and HM.
I guess I should have been more specific, ofcourse information is of the utmost importance. I was speaking more in terms of becoming reliant on the HUD, and not being able to make some decisions without it
