The thing is that, right now, the difference between heavy armor / force and light are just a stand point of having more stamina or force mana pool and regen.
In heavy armor you have at the same time damage mitigation and health improvement.
To put on exemple of what I saw, often against npc like an Tusken Elite I saw a heavy armor character take 20-ish damage. out of a pool of between 800-1500 health depending on vitality, needing less heal when hit.
Where a light/force armor user would take 50-ish. out of a pool of 450-ish health, that can melt so fast. (During events you can get one shoted if 2+ ennemies target you.)
Evasion wise, all armor are the same other than depending on character stat. But with the builds evasion will be mostly the same.Standard hit chance are between 50% - 75% against similar level opponent.
Alright, crafted armor can make a light armor on par of a “vanilla” heavy armor with 18 enhancement slot. Adding 72 defence at tier 4 if all used, or 576 health, 72 evasion, 90 stm or force, etc…
Like heavy armor can have the same boost than light and force (without regen). Or making heavy armor even more mitigating damage.
But the only uniqueness of light and force are that they give a regen.
Basicly it just make heavy armor the standard armor, then Force and Light the “support” one to mix with.
It make full light or force less interesting and unique.
A solution that I would see, it to keep heavy armor as it is.
But maybe add evasion to light / force armor, having a lowered profile, or something to lower npc attention. Where heavy take damage, light evade them, and maybe put force armor in between ?
Just a quick thought.
