To expand on the above, previous MH games worked in pretty much the same way, but each weapon class had a "class multiplier/divider", that was factored into the damage calculation.

For example, the Tiger Jawblade (first stage of Tigrex GS) had an attack of 672. The class multiplier/divider for GS was 4.8, so when calculating damage, the attack would be divided by 4.8, giving 140.

The Rex Slicers (first stage of Tigrex Duals) had an attack of 196. The class multiplier/divider for DB was 1.4, so dividing 196 by 1.4 gives 140; the same as the GS.

So the idea of different weapon classes having the same raw damage isn't new, it's just that other games have hidden the "true attack" of the weapons. Portable 3rd was the same as Gen is, and I personally thought it was a shame that 3U went back to the old way.
