I think the dropsuit upgrades menu is pretty bare....
A new Armour skill would be very welcome, so bear with me ... I'm not good at ironing these ideas

The skill would be passive armour repair, adds 1hp rep per second, per level
the cost multiplier should be quite extreme to make l5 tough to obtain
but this would give all suits the ability to have passive rep and keep low slots

the requirements should be

- Armour upgrades l5
- Armour plating l3
- Armour repair l3

I like this idea, if only I could make CCP see the light

No this would make the Gallente passive repair even more useless than what it is now.

I really can't get behind this skill whatsoever. Let's say this skill existed let's compare a Gallente and a Caldari suit. Let's make them both dual tanked for the sake of argument. So the Caldari suit would have 500/500 and the Gallente would have 300/700. The Caldari has a 25 hp/s on shields and a 3 hps armor with this skill; the Gallente would get 15 on shields and 5 armor. This gives the Caldari an overall 28hp/s while the Gallant gets 20. The 15hps comes from the pattern presented in 1.8 drop suit stats. So not only would the Caldari get a better passive repair they also get better use of the repair due to a better balance in hp, shield suits already have better repair and can get the same HP asn an armor suit. This skill should not exist.

5hp/s is too high for a blanket bonus from a skill, even if it's a massive SP sink.

.2 hp/s | 1 hp/s at level 5

.3 hp/s | 1.5 hp/s at level 5

.4 hp/s | 2 hp/s at level 5 | equal to 1 STD armor rep

It'd be a buff to both armor and shield tankers. Armor tankers could get it for that 1 extra hp/s on top of all their other reps. Shield tankers could get it so they don't need to waste a low on a MLT armor rep or risk running around with half armor because of a firefight 5 minutes ago.
