does no one remember hav or murder taxis? they had the resist mods plus natural resist. however 20% maybe to high why not try 6% basic, 8% adv & 10% to one type per mod. yes there will be stacking penalies but only if you stack the same type of resist mod, cpu/pg of the damage mods, armor ones on high side and shields to low. this way heavies can not abuse them to op levels, the worst heavy to abuse this would be caldari making their armor harder to take out or the Minnie but both have lower ehp the the gall or amarr by 200-400 (easily on protos). logis and assault could stack 2-3 making them more of a defender, resist damage but at the cost of dealing damage.
the resist mods themselves should be broke up like the damage resist of the heavies.

hybrid - blasters, hybrid- railgun, laser weapons, projectile weapons, both having an armor on high slot and shield on low slots.

the amarr heavies would be harder to kill when going up against with another heavy since they have a natural 15% resist the throw another 10% on, however 5% damage mod plus proficiency of the hmg 15% (when in armor) and the natural 10 of being an armor weapon being it to 25% so it is equal damage plus resist,

Are you guys forgetting armor resistance modules would be high slots? An amarr heavy has wahat 1 high slot? Thats sooooooo op. Same goes for Caldari heavy 1 low slot 4 highs no room for resistance modules

NOPE NOPE NOPE.

Resistance Modules fit in the correct racial slot.

Shields- High
Armour - Low

Jace I think adding resistance mods would natively require a rework the sentinel defenses again.

Also you have to remember that the amarr rail resistance is on the shields, which means the amsent isn't as cut and dried as you might think.

The Sentinel suits won't gain as much traction as one might think. The downside to resists is the fact that if you stack resists you sacrifice HP.

This is a big deal. Stacking plates you can get away with buffer tanking. With resists you cannot get away with it as well. You become dependent upon reps.

Further because as resists are no-drawback they need to provide less overall HP than plates. I'm on the fence about how to balance them against extenders because you can spike shield regen through the roof.

For single-damage type hardeners it needs to cap at about 20% ish. Since three plates can almost double your EHP triple stacking hardeners should provide less benefit to raw EHP while providing solid protection vs. Specific damage.

Remember plates protect against everything. But if you four-stack projectile resists to fight other sentinels you will be leaving yourself untanked vs. Rails AR and lasers.

In short yer dead.
