A lot of passive defenses and skills that require no balance and are "put on and forget it" and have no effective counter, should be changed. Some of these passive defenses don't even have balance or equilibrium cost which makes just makes it more silly. I feel these passive/defense skills ruin combat a little and make it less dynamic and more static.
Below I listed some examples of these passive/defensive skills which really don't have an effective counter and I provided some possible solutions them.
1. Trans avoidance - This can't even be stripped in combat as its not a defense and its basically pay credits, trans avoidance and forget about it and laugh as physical classes miss often. A possible solution would be to just delete avoidance all together and refund the credits or make avoidance a mini skill and reducing the effectiveness of avoidance proportional to how many lessons it takes to get trans as a miniskill. Or possibly introduce a skill that can effectively counter avoidance.
2. Shrugging - This is a "put on and forget" defense which requires no skill to use in combat as you just put it on and have your system def it up if it gets stripped. There is really no easy fix for this. Maybe put a negative drawback on shrugging, like every time shrugging shrugs off a venom there is a very small chance the body loses its equilibrium.
3. Aura of Rebounding - Also another annoying put and forget defense which people have systems to auto toggle it on all the time if they want too. A possible solution for this would be to have rebounding dissipate on movement to another room. Shield dissipates on movement and it has a long 4 second balance, why does aura of of rebounding at least not dissipate?
Edit: There are many more passive "put on and forget it" skills, but most are not noticeable, already have effective counters against them, or are necessary to balance the class that I did not mention them.
