Question regarding shield amplifiers.

So, I trained EM Shield Compensation to level 4. The way I'm reading this is that I should get a 5% bonus per level trained when I use an EM shield amplifier. I add an EM Ward Amplifier to my ship (which says it has a 39% bonus) and I get a 39% bonus. I thought I would get a 39% + 20% (from having EM Shield Compensation trained to level 4), but I'm only seeing a 39% bonus. Am I reading this correctly? What is going on??

The EM Ward Amplifier has a 32.5% Bonus, at Lvl 4 that bonus is 39%. Pull the Amplifier module off your ship then open show info and it should read as the base 32.5%.

32.5 x (1 + 0.05 x 4) = 39

As a helpful rule of thumb: everything in EVE stacks multiplicatively. (and furthermore, to find resists on top of resists, you'll have to sort of do it like stats- EM's easy enough to figure out, but when you've got like a 40% base kinetic resist, plus a 39% hardener, you'll get (1-.4)*(1-.39) and such

That makes shield amps pretty darn useless!

If you max your comp skills, amplifiers provide almost the same boost as hardeners without using cap or turning off. It's not useless so much as situational.

If you could trivially get passive amps, with their lower fitting cost and no cap use, to 59% resist why would anyone use actives which only get 55%?

and they said the passive bonus to active reps was confusing and thus should have been eliminated Roll

I think this comic is appropriate here:

Many bonuses are poorly worded in EVE.

I don't get why they can't just show a simply formula in the description

Passive Shield Resistance amplifier resistance = base Passive Shield Resistance amplifier resist * (1+.05 * skill level)

No ambiguity

also going from 50-51% resists gives you more ehp than going from 0-1%. Just because you think you're only getting a little bit of resists you have to actually calculate the ehp you gain before you can make an informed decision

eft is a very nice and easy tool to check these things

you mean other than the fact that they:

take no cap
are immune to neuts
take less CPU
cost less

yep no advantages here . . .

You listed 'no cap' as two advantages, and cost is such a (super) MINOR advantage that it is barely worth mentioning. Although the DS/Faction passives are pretty cheap too.

Active Resistance Fields:
- Give more resists
- Can be overheated for even more resists as needed
- Are the only way to get omni-resists for shields

3 advantages each. Looks pretty balanced. I'd like to see a passive omni-resist amp, but I don't expect it. And if it ever happened, it would have to be accompanied by an active omni mod for armour.

Shield amplifiers are sweet on AFK hauler ships. At least I almost always fit a single EM one.

Margin Trading got its description updated, so illustrate the effect at max level (24%). A bit more eleboration there would be nice, but not critically necessary.

The amplifier thing never confused me, but it'd still be good if they updated it, e.g. to give example resist values at skill 3 and 5.
