Allow me to explain Tensor first.
Tensor, linked from the word, is a special type of tractor beam weapon. It pummels them with the tractor beams own energy, wave after wave by destroying the celluar level. It is a rare weapon type but deserves to be mentioned as such. We don't see it very often but when it does happen, it is perhaps one of the most unique and dangerous weapons in Star Wars.
As for Concussive being Stun, I am opposed slightly but I will work with perhaps a hybrid term such as Concussive/Stun to give a balance between the two. That way, if you are thrown across a room and get shook up in the way you wish, but also hit with a stun ray and fall partly backwards from being shaken around, both can work and both will have the same meaning.
Vibro however I will disagree entirely. Vibro, shortened for Vibroblade, is due to the unique structure of the weapon itself. A
Vibroblade effectively shakes at a ultrasonic frequency, making it much like a turkey or ham like slicer from the deli. It is like a chainsaw...smacking it generally does nothing but once revved, it does more damage than expected. That is what Vibro is meant for, shaking and cutting through armor far more drastically and due to how unique Vibroblades work, be it a ridiculously sharp cutting weapon that has been shown twice to possibly cut through Beskar in weak sections, that is why it is separated in full.
The team have talked before on different sections of Kinetic damage such as Piercing and Concussive/Blunt. The end result has always been, it is still Kinetic and is universally as such, kinetic itself. It has to be a very drastic distinction to change our minds but the idea is that if it shares multiple properties or is very similar to each other, it is not allowed. Disruptors been a keynote to mention before going further as the energy damage is different from an actual blaster bolt.
As for Biological, the issue has been constantly that it been more or less a dump stat. No one really takes advantage and when it does, there is rebreathers and a lot of other gadgets usually in armor to ignore it still. Meaning really, it is useless. We call the hits regardless and this also just made it...not workable.
As for what John was mentioning, no one really needs a large list of resistances unless needed. He just wanted it smaller at the time and there was certain problems with your resistances at the time.
Also I should point out and really wish I did earlier, Extreme Elemental is more or less, perfectly fine for Heat/Cold weather. They can be combined if needed and helps stat work at times. Pressure/Vacuum is generally also been in the past year a combined stat as they are virtually and closely the same.
If any other questions, please let me know. If I missed anything, poke me and I will answer it the next time around. Been a long day and I may have missed things.
