I believe the point Neoxx is trying to make is that the cost to value ratio is really screwed up.
Example, a light bot compared to an assault.
(Based on older prices, but the ratio is still correct)
Light bot value = 800k NIC
Assault bot value = 1.2 mil NIC
Does this seem a fair cost ratio? I'd say yes.
Now, let's compare the problem bots.
Assault bot value = 1.2 mil
Mech = 7mil
Does that even seem close? God no, the mech would be valued at around 2-3mil if it were to be balanced and that's a generous value at that.
Even when you compare mech to heavy mech the values add up in the difference. The issue is that the cost/value ratio is scewed to hell and back when you compare assaults to mechs. The guys in the assaults are damn effective against the group of mechs, and they are risking nearly 1/7 as much. Will the mechs win in a even engagement? Yes, most likely, but they really lose when you add up the mechs that were lost in terms of NIC.
TLDR
It's stupid the way it is, and either medium weapons need overall lower dispersion (I don't recommend it as it screws with ewar/light balance) Or more intelligently, raise assaults surface size to 5m. Done, problem solved, crisis averted, game better balanced, damsel saved, dragon slain, happily ever after achived. Wait, what was I talking about again?
