Its not just 2-3 clips, you need to phrase this correctly. You can literally fire swarms at a double hardened madruger at full intensity and his armor hp will be capped at full until his hardeners run out, it doesn't matter how many clips you fire at him. One swarm launcher cannot do enough dps regardless of fitting to even scratch the repair of a hardened madruger.

Why should it take multiple people to kill a double hardened tank? It was already hard before, unless the tanker was certifiably ********, but the way hardeners combine with reps and armor hp makes it literally impossible now to kill a madruger until their hardeners go down. Why is that ok? Maybe if infantry had modules that boosted their damage so they could overcome the hardeners, it would be fine, but they dont. There is no AV/V balance when you can simply choose to negate AV completely when you fit your tank. Its not even a matter of tactics or ambush, its just straight up impossible for a single person to kill a tank fitted with 2 repairs and 2 hardeners unless the tanker just does not react.

Could you imagine how absurd it would be if infantry had fits like that? Heavies walking around, literally invincible to every weapon on the field, unkillable until their hardeners went down, is that something you are ok with? If not, then why is it ok for tanks?

Well I've said this before but here is what I envision with Armor Repairers becoming active modules and shield boosters having a slightly higher HP/minute.

Natural Armor Rep (~30 HP/s) (Constant, very slow, Supplementary HP regeneration)
Natural Shield Recharge (~120 HP/s) (Delayed, slow, Supplementary HP regeneration)

Active Armor Repairer (Moderate Duration, Moderate Rate, Primary HP regeneration)
Active Shield Booster (Short Duration, High Rate, Primary HP regeneration)

The recharge delay is of course a factor, but is the tradeoff for a much higher natural rate. Even so in both cases that is simply supplementary regen. Currently Shield Boosters are so terribad that shield pretty much has to rely on natural recharge....which I think will remain nearly impossible properly balance against armor repairers, ESPECIALLY Heavy Passive ones.

Most of this **** started when CCP Blam moved us to the "Passive Regeneration is Primary Regeneration" model and it has been a mess ever since. Passive regeneration is fine if it is limited to supplementary regen, but the primary regen moves back to the Active model.

NOTE: I think that currently, the issue with armor repairers lies in the HEAVY ones. I don't think the Light ones are problematic so those can probably be left as is, as not to totally mess up Dropships and LAVs for the sake of HAV balance.

As for balancing within the system we already have....I think Rattati is willing to be aggressive in change if it is absolutely necessary. However if he can reach a balanced state by making few changes, he's going to be more likely to go that direction with it. Manpower is very limited on the Dust Dev side so he has to make very tough choices on how things are done, and if he can get the desired result (of balance) with less work, he's going to take that direction with it.

Its hardeners combined with passive heavy repair modules. The hardeners boost the EHP of the tank quite a bit (x4 for double hardener I think?) which has the side effect of magnifying repair module strength by the same amount, this ends up allowing you to outrep a ludicrous amount of damage just by flipping a switch. This isnt a problem in the gunnlogi since the reps can generally be stopped by damage, but on the madruger the reps just keep going regardless, which results in massive imbalance.

Show me how you got 61% i would want to add it to my mathz when I go to 2x H-aHP tank vs 2x H-sHP

I don't think dual hardeners are an issue but when you are hitting 60% resistance AND have something like 300 repairs per second something is wrong.
