I'll try to give some arguments as to why I think Caldari heavies (sentinel and commando) should receive a balancing pass in HF delta with regard to their CPU/PG allotment.

So, assuming one has pretty much maxed out "fitting skills" - primarily Electronics, Engineering, Core Upgrades at 5, Sidearm/Grenade/Light/Heavy weapon operation, etc. at(least) 4, you can, for example, fit every slot of your advanced suit with all advanced level gear (modules, weapons, equipment), and at least a decent portion of them with proto(complex) stuff. For example, with the above mentioned skills, and Minmatar Logi 4, I can fit my adv. Min. logi with advanced modules and weapons, and fill every equipment slot with proto equipment (Core focused repper, Allotek nanohive, proto needle). This is pretty much the case on every fit I use, or tried to assemble in protofits. And to me, this makes perfect sense - if you invested heavily in "fitting skills", you should be able to go "overboard" with the stuff you put on your dropsuit. At least to some extent.

The only exception to this rule are Caldari heavies. The main problem is their lack of PG, while boasting more than sufficient amounts of CPU. I'll give two examples:

1.
Adv. Cal. Sentinel:
High: 3x Enh. Shield extender
Low: 1x Enh. Armor plate
Weapons: MH-82 HMG, SR-25 bolt pistol, M1 locus
CPU: 214/302 PG: 43/43

Here, we have adv. Cal. sentinel fitting every slot with advanced gear. As you can see, it's PG is exhausted, while still having 88 CPU left. The only reasonable objection one could have to this fit is my choice of SR-25 BP, since it uses 10 PG and could be replaced by something less PG consuming. However even if you do that, you can at best replace one of your adv. gear with proto. But even then you'll still end up with massive amount of unused CPU.

2.
Adv. Cal. Commando:
High: 1x Com. light damage mod, 1x Enh. Shield extender
Low: 1x Enh. Armor plate
Weapons: SB-39 rail rifle, C-15A sniper rifle
Equipment: Compact nano
CPU: 201/286 PG: 47/47

Again, PG exhausted, 85 CPU left. This fit actually has one complex item (damage mod), but also has one basic item (compact nano, which uses only 2 PG). The choice of weapons may be questioned, however, I chose the only two types of weapons that Cal. commando's bonus actually applies to. If you have trouble fitting same-tier weapons the dropsuit is supposed to use by design, something is wrong here.

The only reason I can assume for such CPU/PG allotment is that CCP (Rattati?) tried to "enforce" the use of shield rechargers/energizers on Caldari heavies. They use massive amounts of CPU and no PG at all, so by using them you could probably get a fit that is much closer to using most of it's CPU and PG at the same time.

If this is the case, then I can only say that this is not the best way to get people to use certain types of gear. If an item has less perceived value by the community than the developer thinks it should have, then such methods aren't going to make the item any better. On the topic of shield rechargers/energizers, I can only say that although they're not useless, they will always be an inferior choice to extenders simply because (unlike extenders) one has to survive an engagement in order to have any use of them, and that is usually the trickiest part.

So, to conclude, I think Caldari heavies should receive a 10% buff to their PG. To compensate, they should receive a 10% nerf to their CPU. Since Rattati already mentioned that he plans to further cut the CPU cost of rechargers/energizers, while possibly giving them a slight PG cost, this change wouldn't seriously hinder anyone who plans to use those modules, while at the same time allowing other fitting options.
