I fear that moving the PG unit to high would exemplify armor tanking much more. While it would solve some issues of dual tanking (ie shoving shields in top row just because)

The other issue with the current PG progression is that only two types of players have to deal with it. Newbies; and Top gear vets. People who are between suffer naught from fitting problem. While I do not identify this as the sole culprit there are others issues I feel are contributing to this

First of which is by nature of the game to help keep it lower budget on the network and easier access to the common audience. This problem would be low module count. By nature things very limited in resource typically you are in the mindset of making every slot count. Combine into the environment of shoving in a PG module upgrade RARELY translates into another modules worth of additional power. Thus ergo its far better to just shove a downgrade (which goes back to the issue of not having a tetricide as well; however this is the positive of the current tiered system) that would fit within fitting budget without wasting a module slot at all.

There are a few solutions.

1. Offer something that cannot be obtained by use of another module.
Arguably you can say that PG addition is a unique aspect of the module but Ill retort to the previous statement that some tighter fits can give up a higher tiered module to allow a lower one is just as similar in function.

An example would be additional ammunition in the reserve; however that makes little to no lore sense as I just stated it for an example.

2. Offer expansive hybridization whose performance would be to slot costly to reproduce but the offering on any one aspect is far weaker than specialized module.
IE Shield Recharge; Shield HP Max, Stamina Max, Stamina Recover AND PG

3. Alter the PG of various items (bad route) I feel that this may be a solution but I am emotionally opposed to it as its additionally lots of work and to top it off its vibes of bad enforcement of game play. Positive enforcement should be rewarding not punishing.

its the same way in eve online. shield suits typically run fitting mods. whats backwards in dust is that damage mods are high slots.

damage mods are supposed to be the hard counter to high eHP fits, but instead we give armor tankers high HP and high damage... as well as rep tools, armor hives, and needles. its a wonder anyone shield tanks at all around here.

and yes shield tankers have to fit cpu mods... which is exactly why a 3/1 and 4/1 slot layout for cal assault is broken when we also need a regulator as well

In original concept that was breifly explained by the former CCP Jian then massive further assumption on my part...

there was supposed to be a built in balance mechanic to stop "Dual tanking" Shields where supposed to be Primarily CPU based in the requirements needing to fit it. And naturally the more shield favoring races would have bonuses to CPU capacity and very limited Power grid.

Where Armor was supposed to be Primarily a Powergrid requirement module. And then armor suits would naturally have signifcantly higher PG and limited CPU.

Both suits would then need to sacrifice, for example; shield suits would have to sacrifice a shield slot(Highslot) to fit a Powergrid module to then fit PG intensive modules.. Sacrificing your specialized race bonuses for a sandbox fit that may be better suited in certain circumstances.

Where Armor suits if they needed extra CPU, would then have to fit a CPU module in low slot and sacrifice their Tank, for shield or CPU intensive modules.

Between this and the original concepts of "Meta" there was supposed to be a Synergy created with auto balancing the suits.
