That's the worst argument for balance I've seen in a while! It's all well and good to say that someone should have scouted for experimentals, but Monkeylords are stealthed naturally. You'd have to keep vision of your entire territory in order to see it coming. Now, that's easiest to do with t1 airscouts, but it just so happens that a monkeylord has an AA range of 64, and a scout has a sight range 42. So any Monkey with intel is going to kill your scouts before they see it.
so that is completely false (pls don't spread false information), since scout give intel until crashing. (and it travel a lot while crashing).
And ML aa, are slow, and doesn't kill the scout at 64 range. but more at 20 range.
The only thing is that you can vet ML with scout. I already watch a game where ML vet twice thx to spam scout, and allow the guy to win the game.
BTW (for turkey), taking fight between ML and harbi as exemple isn't really relevant, since ML nearly hard counter harb. ML is the only exp that can attack while running away, and you can use that to kite harbs, or at least engage a portion of the harbs army. The only way to kill a ML, is to get a good engagement on multiple front.
