Well that is because you don't know how it work. Wep focused is not that good how it sound actually. After nerf of ENG and SYS regen especialy.Capacity is the total load your Capacitor has before it runs empty and needs to be recharged.
Personally I don't see the reason to do any PD mod other than WEP focused but YMMV.
Get capacity for high alpha strikes (PAs and rails) and get charge for more sustained fire.
So theoretically if I want more boosts I'd want an Engine recharge or Engine capacity upgrade. But which is better for that, overall?
If you want the absolute maximum sustained boost rate your ship can manage (4 pips, boosting every time it has enough charge to do so), you'll want to get grade 5 Charge Enhanced, as it can give up to 29% more recharge rate at the cost of at worst 15% less total capacity. The capacity has almost no relevance if you're doing an activity that needs a constant amount of power, as then you need high recharge rate.
Yeah as it stands I think charge enhanced is a bit too good. If anything the capacity needs at least a 15% extra to make it worth having. But still the loss of recharge for them still makes them a poor choice.
The SYS upgrade is the most useless by far though.
Why upgrade SYS cap and regen when the only reason SYS drains is shield damage, which doesn't regenerate in combat and the upgrade doesn't effect the shield hardness value from pips?

Yes, I'd currently only go with Charge Enhanced as well. Imo, with proper pip management to make up for the slightly lower capacity, you just can't beat having as much recharge rate as possible. And except in some very select few situations, the specialized upgrades are worse overall because their recharge rate is lower than Charge Enhanced, so the only benefit is the additional capacity but at the cost of capacity and recharge rate on the other 2.
Personally, I think that the Focused upgrades should be able to boost their single focus to a higher recharge rate then Charge Enhanced can overall
Doesn't regenerate in combat? Why doesn't it regenerate in combat for you ...?
Every sys module (as noted on the modules tab) uses sys energy. Shield recharge is by far the most notable one, but an ECM charge will also take a chunk off it not unlike boosting from eng.
Having a larger and faster recharging sys is pretty useful, because that means you need to put pips into sys for a shorter amount of time to top it up and can run without any in there while not taking fire. You get to be faster and deliver more damage.
You don't have a choice there. When you decide to improve just one capacitor (at expense of the other two), you improve both capacity and recharge rate.
The choice only exists for either improving all capacities or all recharge rates.
As already mentioned high capacity is only useful for alpha/burst energy. Any time you want to output a lot of energy at once just from the capacity store, regardless of pip levels (which is shield recharge/ECM, boost and weapon cooling).
So theoretically if I want more boosts I'd want an Engine recharge or Engine capacity upgrade. But which is better for that, overall?
