I started this thread to make a list of units that a 20 model unit of glade guard should go from two ranks of ten to 4 ranks of 5 for, to try and win combat. I bring this up because i recently played lizard men, and a unut if cold ones charged my unit, and wiped them out. I lost combat by 4. He charged, and had a banner, and killed 5 glade guard. I had a banner and killed one of him in my stand and shoot, and had a rank. I rolled a six and fled. My thought is if I move them from 2 ranks to 4, I probably don't kill one of his cold ones Ub the stand and shoot. So he would still have a combat res of 7. I would have a combat res of 3 still. However if I did get the kill in the stand and shoot, then i would have combat res of 4 and pass my ld test. Which would be awesome to tie up that unit for a counter charge.
So I want your imput. What units should i or shouldnt reform? So numbers of models in an enemy unit matter? The type if unit and so on?
