@epeli you are right about cryokinesis being a hybrid damage type, i forgot about this. But if there are more hybrid attacks in the game it only makes this change more necessary.
It's important to notice a difference between hybrid damage type and multiple channels of damage (which can use different types or not).
Electroshock weapons would fall under multiple channels category. They have mechanical and zap damage types. Both channels would need to go through full DT. Just like burst or magic missile from D&D - multiple projectiles, each of which needs to go through DT separately.
I have 2 more cards i'm gonna use to convince You to my suggestion.
1.
There are energy shields in game. They are using DT mechanics to reduce damage. The difference is that any damage absorbed by shields is substracted from shield's capacity.
What happens if we shoot plasma at someone with his shield activated? believe it or not but damage from plasma (whole damage) needs to go through shield's DT only once. There is no separate substraction for fire and plasma. If plasma damage is 120 (60 fire, 60 energy) and shield has 80 DT vs very high speed attacks, damage that will bypass shield is 120 - 80 = 40 (20 fire + 20 energy). Not 0.
Game is inconsistent here.
2.
Say we have 25% fire DR and 75% energy DR. We get attacked by 100 dmg (half fire, half energy). What damage should we take? The answer comes easily - it's 50. And this is correct answer.
Why 50? Game takes
average* of your fire DT and energy DT and uses it to reduce damage.
(25% + 75%) / 2 = 50%
100 - 100 * 50% = 50
You can try it with different DR values if you wish.
But if damage is reduced by DT it has to go through
sum of fire and energy DTs. Why SUM and not average this time?
That's another inconsistency.
* This is actually weighted average but since damage is split exactly in half between fire and energy it gets reduced to normal average.
You mean with a high level attachment I can create a weapon that nearly always crits? Damn, I gotta try that.
No. I mean energy weapons get increased energy consumption (to already high consumption) by installing attachments.
Really, energy weapons, plasma in particular, suffer from problems other weapons didn't even heard about
