Ok let me clarify some things for you.

"Gallente is getting the old (current) passive armor rep for every suit."
1 HP/second for Gallente Heavy. That will take 8 minutes, 45 seconds to completely rep with no modules or HP skills. It's a token bonus that does effectively nothing. This is not a skill that goes up per level, Gallente heavies get this 1HP passive rep and that's it.

3hp/second for Gallente scouts. Considering limited slots and resources, this is so they don't fall behind the Caldari and Minmatar scouts in terms of HP regeneration. Considering how fast shield recharge is? 3hp/second is quite crappy in comparison.

"G Heavies get the most popular resistances (Rail Rifles, anything Minmatar), and they are going to have 4 lows, which are easily the most versatile slot in the game!"

So when a ton of people roll Gallente Sentinel, do you think people will continue to use RR and CR as much when the G Sentinel is resisting their damage? No. People will use a different damage type that does more damage. The Sentinels in a way encourage diversity of damage type.

G Sentinels also have the lowest damage output of any Sentinel with only 1 high slot.

"G Scouts have 3 passive armor reps, and the lowest scan profile amongst scout suits, which is a HUGE deal."

Gallente's role is typically scanning and other targeting electronics, this is similar to how it is in EVE. Gallente suits are simply going to always be the best at scanning and avoiding being scanned. In exchange they give up other advantages that other scouts get such as stamina and better cloaking abilities. Is it a valuable bonus? Of course, but it doesn't mean its the ONLY good one.

"G logis, if the rumors are to be believed, are getting enhanced scanning abilities, to pick up anything BUT G-scouts, or highly-gimped other scouts (due to having to use multiple complex dampeners)"

Again, Gallente are always going to be the best with scanning. However in order to gain this ability they sacrifice other support roles such as armor repair, uplink efficacy, and nanohives. Useful, but not the only useful bonus.

"Caldari have that ridiculous heavy with the 1 second shield charge delay!"

It's a 4 second delay, 1 second depletion delay. Dev already stated that the 1 second part was a typo. Chill out.

"Now... Minmatar Heavy gets resistances to all the scrambler rifle spam, and blaster rifles, of which you might see one or two per game. Not to mention, the negligible 20 point speed increase, which is paid for by about 90 less EHP, and will be completely negated when you consider Gallente's 4 lows for KinCats/armor mods. Minmatar at proto level get 3/2 H/L which is a serious disadvantage."

Higher sprint speed with 2 low modules for armor/speed mods and then a shitload of damage with 3 highs? Minmatar will be fast, hard hitting Sentinels that will require a different kind of playstyle than other Sentinels but is valid nonetheless.
