Good call, Waywatcher is now General - with Masterful Hunter - +1 to hit, I think, to help snipe heroes. The EG's role is to hold objectives. The SotW and WWR are hopefully going to gang-up on the greatest threat supported by a Waywatcher and Nomad Prince and eliminate it or them turn one. The cav can be held back for later or thrown in at the beginning once I know what I'm facing and in which scenario. The Spellweaver can stay out of melee, probably with an EG unit, is -2 to missile fire and can now unbind from 30" away. Also I can take first or second turn. 1st turn so they can't put up defences or 2nd turn to gamble for the double turn. I'm pretty sure I'll be the only one-drop list.
Unfortunately, we don't have great damage output to begin with, so If I can take out one flank at the beginning, I'll have less coming back at me and hopefully can hold onto objectives long enough to score points. We can't survive a stand-up fight, so I'm going for the ambush.
