Fair enough - as mentioned I have only played 3 games so my thinking can be(is) way off - so I really don't have the experience
I have bad dice luck.. but I find I am better off rolling a crap tonne of dice to get some hits vs only a handful of dice.. hence why I run skinks

Especially for the cost price I can run a lot of the skinks vs guards/warriors.
If our elite army could sustain at least a round of battle, then I would consider them. Right now I don't see the value of running things like warriors and guards over skinks. Shame as I have a lot of nice models but not worth playing them - sure fluff reasons or for rule of cool but you still want to be able to be competitive vs just feeding bodies to your opponent.
Same as our Knights - the models are 'ok' but I have 15 of them all painted up and they look great on the board.. charging lizards.. but I have not been able to make them viable. Yes they have 2 wounds a piece, but then go down really quick :/
