What most people fail to realize that when people say "logi is OP", they don't mean that logi is simply a better fighter.
It's that they're pretty much the same as the assault (with a few swaps, like less speed but more eHP) BUT get 3-4 equipment slots.
When people stack plates and extenders in these threads to show that logis aren't that far ahead eHP wise, they fail to realize that stacking plates and extenders is not the best of suits.
Here are my logi and assault suits, each are designed to push it to the maximum, I have been tweaking my suits for ages and these are the optimal one's I found:
Note: I have CPU/PG skills maxed, I could not push this suit further.

Gallente Assault:
High:
Complex damage mod
Complex shield extender
Complex damage mod

Low:
Basic plate
Basic plate
Enhanced armor rep
Enhanced armor rep

Weapons:
GEK 38 Assault rifle
Syndicate SMG

Grenade:
M1 Locus

Equipment:
Allotek Nanohive

Armor: 449
Shield: 217
Combined: 666 (huehuehue)
Damage bonus (skills not included): 20%
Regen rate: 7.5hp/s
Movement speed: 4.81
Sprint speed: 7.08
Stamina: 157.50
Stamina regen: 15.75

Not bad right?

Now let's look at the Gallente logi:
High:
Complex damage mod
Complex damage mod
Complex shield extender

Low:
Enhanced ferroscale plate
Basic plate
Basic plate
Basic plate
Enhanced Cardiac regulator

Weapon:
Duvolle Assault Rifle

Grenade:
M1 Locus

Equipment:
Wiyrkomi Triage hives
Wiyrkomi Triage hives
A-86 active scanner
Ishukone Gauged hive


Shield: 181
Armor: 560
Combined: 741
Damage bonus (skills not included): 25% (I could fit a duvolle on my logi, which has +5% damage over a gek)
Regen rate: 5hp/s (Inherent logi regen)
Movement speed: 4.54 m/s
Sprint speed: 6.67m/s
Stamina: 198.19
Stamina regen: 22.89



Conclusion:
Seems pretty legit right?
The logi has more damage, more eHP, more stamina and more stamina regen for the price of speed and a sidearm right?
Oh wait, but that would only be legit if both were combat focused suits, I.E both have one equipment.
But the logi has 4 equipment slots, making it far far more verastile and just a better deal overall.
Especially with the 6x triage hives I fit on my logi, I am ******* invincible inside one of those.
Low on health?
Plop a triage hive, return to battle faster than shields can recharge.
I also couldn't fit a scanner on my assault, making me much more blind.
Also, I could fit a kin cat instead of a regulator to be even faster than my assault, but I prefer the sustainability that regulators provide.


How I think this should be solved:
Two problems that I see here:
1. Logis get 5hp/s on armor inherent, which allows me to give up on a armor rep and put on an extra plate, increasing the eHP gap further. HOWEVER CCP said they will change it once they have the infastracture to do it (something about the code doesn't allow them to put on a more logi orientated bonus)

2. The CPU/PG gap is just damn too high.
Could solve it by either reducing the CPU/PG on logis, forcing them to decide on either being a combat suit or a logi suit, not both, OR increasing the CPU/PG on the assault. (Should also buff the scout CPU/PG and heavy CPU/PG if this is done, just to be fair)
