Dojo - Why Am I Not Running The Same List Twice?

Serious question. I used to always be an advocate of doing 2 lists that do drastically different things, like playing an infantry skew and jack list or shooty list and melee list or whatever. But real talk, the most successful streak I've ever had playing WM/H was playing Trolls with basically 2 of the same list (2 arm skews). And I'd just pick whichever one had better tools into my opponent's armour answer. So with internal balance being a bit of a trainwreck in Cryx I might try going back to this strategy.

Worth a try, to say the least. At least until I get the models to mess around with a Lich3 brick.
