That's true. It's a different take but a lot of people will probably just do that; play your own game, and if you face DG, it's just an L and move on.
I am having fun trying to shift my 'ideal' White Scars into something different that can evolve into a better all comers type list.
Personally, I always found myself a bit... too aggressive with my White Scars. In those match ups where I faced something that was very good at handling a charge, or simply just dishing out a lot of close range/close combat damage, I would be too quick to get in with the Scars and often I'd nearly lose as a result or suffer a very unnecessary loss.
Lots of what 'clicks' with White Scars is not even necessarily tied to Close Combat. I've realized this over the past year or two. Having speed, and strats that assist with speed, and even their Psychic powers have great utility.
I should be able to make a list that can concentrate on softening up targets just using marine based units that do this well for every chapter. Then capitalize on the stuff that Scars do well in T3+.
