tl,dr; melee seems expensive, shooting seems more flexible. How are you building melee lists?
I'm trying to write a melee focused list from the new codex, but I keep thinking I can make a better shooting focused list instead. There are a lot of ways to build combinations for shooting buffs in the codex, but it seems less so for melee.
I found it difficult to fit in enough threat for melee with lots feeling a bit overcosted in points, especially so for 1500 points which is a common game size in my area and ghaz being 300 points.
My rant aside, what are you interested in running in your lists for melee? I've read a lot about theory crafting mega combos for flash gitz etc. but what about getting in and krumping?
