How do?

More of a general chit chat topic than a plea for tactical assistance.

I've been working on and tweaking my Skitarii army, and I've found myself breaking the habit of a lifetime and putting together specialist squads.

See ever since I got properly started back in 2nd Edition, I've been used to a more flexible approach to squad armament. Good example are Tactical Squads. If one had a Meltagun, their Heavy Weapon would be a Heavy Bolter. Flamer? Lascannon would be paired. Theory was my squads could then each deal with pretty much any threat, making it harder for my opponent to neutralise any one area of dakka.

Another part of that was one of necessity. I didn't have the disposable income I do today (of course I didn't. I was like, 15 at the time, tops) so instead had to make do with what I already had and what I could convert up (badly, as it often turned out).

But all of a sudden, I'm fixating on right tool for the right job. For instance, a squad of Skitarii Vanguard with three Arc Rifles can mess up nearly any tank in a single volley, spesh if it parks within rapid fire range. Not quite sure what's caused this change in philosophy though.

Anyways - scene is set, so do tell how you go about it?
