Rather than fixing the profile they could just make a box of four, with two of the sculpts holding the Pulzars, so people will buy them as Auxiliar proxies.
Or better, A box of 4 Chaksa Longarms and a box of 4 Reesculpted Chaksa Auxiliars :p i want them ALL!
Portable auto-cannon Chacksa linked in Haris with 2 cheapest Brawlers, and (at least now) we getting BS12 DAM16 B3 AP+EXP. Im not that sure how good this is in N4 comparing to all changes we've got, but comparing to N3 does not sounds that bad...
I dont think you can mix chacksas with brawlers. For haris team you need troops from the same profile, thats the difference between triad and haris. At least the haris swc tax is lifted. Still with the base chacksa profile being 22 points its a hard sell for me personally. I'd sooner use the Reex K1 marksman in the special triad, or a Draal AP marksman in tricore for active turn anti heavy armor.
My bad, sorry. Never used fireteams other than Triad Still, I would give it a try, at least few times before stepping back to usual APMR Draal or Kosuil with K1
