Why did all weapons get a cost increase when laser became free?

When laser beam become free without morph at level 1, why did the other weapons effectively get a +5 increased cost?
The level 2 weapon morph used to cost 50 for the weapon with an additional cost of 25 for the morph totaling 75. Now it costs 5 for weapon plus 75 for the morph totaling 80.
Beam laser is competitive with the other weapons and is arguably one of the most versatile and least specialized weapons. Personally, I will see little reason to morph into any other more specialized weapon when 80 metal is almost enough to buy me another Lotus turret.
If the goals were to decrease commander variations in 1v1 and make commorphing pretty much obsolete in 1v1, I think this achieves that.

The cost of accessing a non-laser weapon is 80m though because it bakes in the first morph cost.

Laser gets 50m off that cost as a credit that you never have to pay back unless you morph, essentially subsidizing commanders who never morph.

Maybe the morph could increase some other stats besides giving the commander a specialized weapon? You don't have to choose any other weapon, but the base morph cost should at least give you some hp/mobility/.. then.

Well it already exists, but for the first morph it's very minor I believe. Econ comm gets more BP, Guardian more HP, Strike more regen and Recon more speed. If it was more substantial for the first morph it'd compensate for the cost.
