my 1k list, soon to be 2k list

here is my 1k list. It is designed to be more balanced than my latter.

HQ- Shas'el with plasma rifle, missle pod, hard-wired multitracker, targey array

Elites- 3x crisis suits missile pod, plasma rifle, multitracker
2x crisis suits missile pod, plasma rifle, multitracker

Troops- 12xkroot
7x fire warriors
6x fire warriors

Fast Attack- 1 pirahna with flechette dischargers, fusion blaster, target array
6xpathfinders w/ 1xdevilfish

Heavy- 1 hammerhead with target array, railgun, burst cannons, multitracker

My 2k list will look something like this

HQ- same as above
Elites- 3 units of 3x crisis suits configured same as above
Troops- 10xkroot w/ 5x kroot hounds
10xkroot with 5x kroot hounds
6x fire warriors w/ devilfish
7x fire warriors
Fast attack- 2x pirahna same as above
2x pirahna same as above
6x pathfinder same as above
Heavy- 1x hammerhead same as above
1xheammerhead same as above
2x broadsides with slow and purposeful


My thoughts are I'm going to walk my fire warriors on late in the game, drop my pathfinders off, and come back to get fw's to hold objectives. If someone were to attack them, they would be wasting fire power late in the game that should be going towards those heavy choices, or more importantly, those 10 fireknives.

What are yalls thoughts on it?
