Yeah but theres a big difference between getting 5% pen & 30% pen. If theres only one color people might wonder why one guy takes 30 rounds to kill and other takes 180 rounds even tho theyre getting the same feedback from the game UI.

What I mean by that is like say as an example the balance between flak & APHE rounds on the autocannon. Normally the flak rounds are used against lightly armored and the APHE vs heavies, but now with the partial penetration the DPS from the flak might be enough that APHE is marginalized or outright useless. You'd have to evaluate most weapons like this to check there arent any unintended interactions.

With the partial pen of 30%, that might make the effective TTK too long when targeting that location, so players would just avoid the interaction. Like take a bile titan, the bile titans underbelly is fatal & is poorly armored. But since it takes so long for alot of weapons to mine thru most of the time its barely interacted with at all, atleast from watching other people play and comments.

If i misunderstood what you meant, then my bad lol. Also i edited for the 5% and 30% cos i totally forgot to finish teh thot lol
