Boy, am I having issues.
Fluff-wise, I'm keen to keep my light company as a light company (no vehicles) and from tinkering and playing around with ideas, lists and practice games I'm finding it hard to convince myself that an all-infantry force is as viable as it was under the old codex. I ought to point out that I'm still trying to work a basic list without special characters, just for comparison's sake (but see below).
My first reaction was to assume I was simply mourning the loss of the flexibility from the old Light Infantry doctrine, but I think it's something else: although my infantry are slightly more numerous these days points-wise, they're markedly more fragile...especially my poor ol' heavy weapons teams. Their specific weakness in the face of Str6+ weapons is compounded by the army's generally lower Ld.
Mind you, this seems to be somewhat balanced by the spectacularly fun (and reassuringly fluffy) special weapons squads! Asfter all, I've been having great fun with both flamer squads and melta gun/demo charge combos.
Please don't think Drax is being stubborn and not embracing the changes embodied by the new Codex - it's just that I'm trying to enjoy a successful and fluffy inf-only army and...well, I'm simply less convinced than I used to be.
The options I've been trying so far for my light company include:
(a) three platoons of two inf squads w. attached hvy and spec. squads (3 of 2+)
(b) two platoons of three inf squads w. attached hvy and spec. squads (2 of 3+)
and - the fluffiest (and costliest) -
(c) three platoons of three inf squads w. attached hvy and spec. squads (3 of 3+).
I used to use one inf company (3 of 3) and elements of a separate heavy weapons company for fire support: now the fire support must be organic to the company. I quite like that...although it does mean that my platoons can't easily be equipped in a uniform way. So, I guess for fluffy battles I'll probably go for 3 of 3+ weighing in at a little over 1400pts (or 1500 with a Commissar Lord)...
...But I think Drax is going to have to start playing mixed lists more often. With 55pt chimeras and some interesting new options, I'd be a fool not to. Multitudes of veterans and stormtroopers beckon too, and I reckon I'll soon be trying out more special characters.
Watch this space...
