A frequently observed problem in game is a lack of wingman consideration, i.e. lead with power at the forward stop, leaving wingman no choice but to use WEP. A good formation lead will always leave the wingman a power advantage during climb, cruise, and descent. If this isn't done, the result is a string formation of planes "going same way same day", a fairly common sight in game. 
So true! I also see players having trouble keeping up because the lead calls out 1.1 ATA and they use 1.1 and fall behind! I try to explain the lead is just telling us what MAP he's using and we have to use whatever amount is required to stay in position.
Myself,I'm constantly adjusting throttle to stay in position,but like you said Puma,a good lead will reduce power so that the rest have reserve power to hold position!
