co(together)+operate(act,work) I think that answers why you were asked to do so. That's why we have training partners.
Of course we could have training 'obstructers', which would be the opposite and thus lead to no training.
So until we recognise cooperation as a vital ingredient we cannot move forward.
Such statements as cooperation is bad thus never make any sense to me at all for it is vital and only a matter of degrees of and with what.
This one seems a little out of sorts for me...not sure what you are talking to.
I never that cooperative training was not part of the mix.....it is that most are tooo cooperative, are not in themselves stable in moving, often it not always double weighted to one side..... So how do you get your pairs past this?
