no. training my DL/DC, DC/DMC, DR/DC together and one by one. same with front four, they share AML/R position and training together quite often. same with 3 MCs, in bit lesser extent, as they have diferent 2nd possition and SA, not together that often..
but yeah, I train groups whenever possible to compare easier etc
maybe don't have great sample, only 2 full seasons, but no.
but there is one sweet little thing I've noticed about group training: when they are close to 30% condition, give them easy or medium drill, just to pass under it, to get to 28 or 29%.
hit repeat button, you'll get to refresh whole group watching one ad. note that it will still be only 15 condition points, distributed evenly. repeat, repeat, repeat. that way you can have your D or M line move up as one, only difference being preprogramed talent.
