They will never increase training. I don't see how, it would  create team   revenue  from the market ,which is very much needed. BB  know's what really needed.
 I think they  did ok job with  training out of position, but I don't  see the real purpose of it.? will  it create better players? IN my opinion ,No. To me I don't see  how it help create better than solo (1 position) or is faster.? its just  same method of training.   BB  is  a big mans  game not  a guard game. This doesn't lessen the cost of anything?  Actaully it set  your team back some what, because  there a penalty attached. Which I'm not surprised by..
 No  point in doing that  training with a penalty..  The easy answer is to give Sb /  Jr lower cost to do increase the price of IS. And  OD, ID.  Not add some penalty on training.
  Its no point in using the  same something for the same results.  It nice to have  a perk ,but  they didn't go about it in a popular way. All it does is help defenses get  better.   IN my opinion  OD/Id is way to strong
