Skill Discussions

I've heard there are a couple of tight fits on hybrid ships, where V helps.
And I could see where Armor Rigging V would be a miniscule improvement.

In general though, probly close to 200 skills that are more important.

I got all but one to V. May have to do that one as well if they introduce more rig drawbacks as hinted in the most recent devblog.

The first one I got was projectile rigging V for a very specific Vagabond fit a few years ago.

the only rigging skills i would consider get to V are the weapon rigging skills, specially Hybrid and Energy. Missiles and projectiles are a no, unless you have absolutely nothing else to train. you can replace tank for meta with a 5% loss in resists and save a lot of CPU. and ACs get a 2-3pg reduction per gun (with two projectile rigs), compared to 9pg reduction on the extenders if you train shield upgs to V. and if you are strapped for PG with ACs its usually because of dual LSEs or because you are drunk and fitted Artillery by mistake. and if you intend to fit arty, you will need a fitting rig or lowslot regardless of your skill in projectile rigging, if you also want a MWD and some tank.

comparing downgrading a shield tank due to CPU to downgrading plates or using a low slot for a fitting mod because of a lack of PG with rails or beams its not a fair comparison. 800mm plates are crap and fitting mods on armor ships are painful.

astronautic rigs are probably the only other ones worth it, only because of the Hyperspatial rigs. you either use none or three (regardless of their new stacking penalties) and the CPU reducction can make any fit hurt.

shield rigs are Meh, you are looking at an average 4 sig reduction, it makes no difference on damage application. and if you want to sigtank, you are tanking on the wrong layer. :o

Rigging applies negative stats to your ship, training reduces those penalties. So yes, if you use certain rigs often, training to V is worth it. Considering they are only 3x skills, they are trained to V very quickly.

Shield rigs, for example, bloom your sig radius. So while slapping on rigs may give you more raw HP, it also makes it easier to lock and hit you in the first place.
Since the basic modules already impose some penalty (such as sig radius for shields), the rigging is further stacking those penalties, and anything you can do to reduce that impact is worth the training time. A full 10% impact per level is also a strong skill bonus compared to the usual 2-4% for most skills per level.

IV is certainly fine for most people, and the majority of my rigging skills are at IV. But I use shield/armor rigs on virtually every ship I fly, and have trained both of those to V.

I'd like to point out that the 10% is actually 10% off a drawback that is, itself, less than 10%. So you're actually looking at close to 1% reduction in drawbacks on most rigs. This usually matters with weapons, which have CPU and grid costs in the hundreds, but for shield and armor rigs, your time is better spent training Armor Honeycombing V or Acceleration Control V.

Just on the numbers for shield rigs.

The baseline penalty is +10% sigrad IIRC. That drops to 5% with the shield rigging skill at 5 (as opposed to 6% at 4).

If you are fitting +EHP shield rigs, you are probably fitting 3 (or 2 on T2 ships).

So it's the difference between 6% + 6% + 6% (19.1% because of multiplicative stacking) and 15.76%. That's fairly significant - while being locked ~3% faster doesn't matter much, being tracked ~3% better does. As does giving a 3% stronger signal to anyone trying to find you with combat scanner probes.

I'm not claiming that shield rigging 5 is a high priority skill for everyone, but it is not a terrible skill either.

I trained Drones Rigging to V for a specific Ishtar fit when it still had dreadful CPU issues. Since the HAC tweaks, it's no longer needed. That said, other posters are quite right; if you're using 2-3 similar rigs on a fit, then the relevant rig skill at V is going to help. I'll eventually train them all to V since pretty much nobody else does ;)

PS - Forget Jury Rigging to V unless you want to build T3 hulls. It's completely irrelevant for anything else.

If you need to train a rigging skill to V you will know. I needed Drone rigging V for some very specific Domi fits - well worthwhile for me.

Conversely if you don't have a fit or a situation where XXX rigging V is needed (you will know) then don't bother training. As was pointed out Jury Rigging V is just not needed for most pilots, ever.
