Better and faster repair packs

[Red_Katana_001]

TL;DR: a Mk2 repair pack, and a few researches to increase repair speed

slightly longer version:

this would add a few researches, one of them being the unlocking for a mk 2 repair pack, which would have more health, and repair faster, and after that a few researches that increase the repair speed, but only a low percentage.

a possible specific configuration we came up with would be

research 1: 'advanced repair packs' would require 75 for red, green and blue science, unlocked after advanced electronics, this would unlock repair pack Mk 2/advanced repair pack, and would cost 2 normal repair packs, 1 steel plate and an advanced circuit to make 1. it would have 600 durability (double of a normal one) and a repair speed of 3 (50% more than normal one)

research 2: 'faster repair 1' this would give a repair speed boost of 5% at a cost of 100 packs of red, green and blue science

research 3: 'faster repair 2' this would give a repair speed boost of 10% at a cost of 150 packs of red, green and blue science

research 4: 'faster repair 3' this would give a repair speed boost of 10% at a cost of 200 packs of red, green, blue and purple science

research 5: 'faster repair 4' this would give a repair speed boost of 10% at a cost of 300 packs of red, green, blue and purple science

research 6: 'faster repair 5' this would give a repair speed boost of 15% at a cost of 400 packs of red, green, blue, purple and yellow science

[Byproduct]

When would I need faster repair speed? It’s pretty fast as is.

Upgrade systems are fun only if the upgrades are meaningful.

Yes, unless you use rocket silos as defensive walls, I struggle to see cases where a faster repair pack would be of much additional benefit, nor do I see compelling reasons to make the MK2 repair pack over more MK1 repair packs. The speed of repair is never the limiting speed of anything in factorio.

If the MK 1 repair pack only healed things to half health, I could see a possible niche, but otherwise, no.
