We might want to look at the impact that would have on Pathfinders.

If you had access to a ML upgrade for FWs would you still take Pathfinders?  I know that the other ML units would still have place, but I could see where that might make Pathfinders a less viable choice.

Not saying it couldn't work, but just something to be aware of as a consequence.  I am all about units having their own role after all.

However perhaps it would be ok to allow the ugprade to be 75 + 25 for fish?

Actually, ONLY Crisis suits are two spaces each.  Broadsides Stands are the same 'size' as an Infantry stand, since there's only one Broadside and a couple drones per stand.

In the grand picture of looking at the whole FW + Pathfinders formation [the devilfish is] 25 points out of 300.

So maybe that's not so bad, but it galls me nonetheless.  You have to admit that it feels different leaving behind a 25 point Devilfish with real firepower compared to leaving behind disposable Rhinos.

Basically, I find it hard to justify ~50 points per infantry model (for Stealth or Pathfinders sans Devilfish) just to get MLs in a FW formation.  It seems much more cost effective to field those separately and that certainly explains why people choose the other options.
