For L templates on SoD - 4 minutes ONLY!!!

no no and no again! 4 is too little - even on SM where there is far less "fiddling with secondary heroes" than on MM6 it is really too little - sometimes 6 minutes is not enough to carry out what you have planned, and on 4 even in turns without grand strategy you have to resort to cockroach racing
2 Wlk777 why don't you try taking a Griffin Conservatory tier 3 far away in the snows with a second scout hero on a 4-minute timer, so that you can then give the army back to daddy in the same turn ;)
