I'm normally a Wood Elves player, but am considering a second army, and it may end up being the Lizards. A lot of the units, I look at, and see value. I can see how they'd be useful, and that they're not a bad expenditure for points.
But I'm struggling with Kroxigor.
They seem like a lot of points for something that will frequently be hitting on 4s, and hitting last, and only has Toughness 4. I've heard that most people feel you really need to run them in skink blocks (skrox, I believe it's called). But then don't you get the problem of skinks dying in droves and this negating any CR generated by Krox kills? Or is this a unit that's only for flanking or picking on armoured cav units and the like (i.e. intercepting a unit of knights and using the krox to get through that thick armour).
How are Krox regarded? Must takes? Never take? Sometimes? How are they used to get value out of them?
