Yeah, you need to distinguish between suits themselves being redundant and passive skills being desirable. It's a fact that most of the specialization suits are identical in stats to the basic frame. The passive skills obviously differ, it's just a question of them being "good' or not.

It would probably depend on how the specialization suits are balanced. If you give Assault Suits better HP than Basic Frames, that magnifies any shielding effect you give their passive, right? If the shields are balanced on a delay system (there's both "completely" depleted, and just depleted regen delays), a passive shield regen per/sec would seem to screw with that and always give them the best of the two numbers. Assaults already have much higher shield regen compared to say, logis or heavies. The delays aren't necessarily different either (in the cases where it is, it's usually the fully depleted, which you'd be eliminating with a passive).

As a bonus, it basically ignored the difference between shield and armor mechanics - the old Assault Passive was already geared towards boosting their shield regen.

The shield recharge differences are currently much greater because of the Assault Passive. Mind you, the only reason the Logistics such as the Caldari seems to have an edge is because of its passive at the same time. However, if you take into account both passives at the same time, you need to add 25% to every assault number you have on that list. So, the Cal Assault becomes 31.25 hp/s compared to 20 hp/s (over 50% higher). In the end, that sort of regen is probably more useful than a trickle gain like the armor rep.

That aside, the aim assist thing just seems like it'd annoy a lot of players, as CCP is pretty horrible with their aim assist mechanics currently. You'd drive more people away from the class.

Giving the highest HP class in the game both damage resistance and higher speed seems incredibly imbalanced. What exactly is the drawback of being a heavy at that point? You can take more damage than anyone else, and charge across the field.

Cloaking when immobile would make scouts invincible snipers (as well as be generally overpowered in other circumstances), and again, would be horribly broken.

You told me to skip to post #6 where they're described as passive skills. I think the weapon/equipment menu is awkward and buggy enough without trying to add active skills to it anyhow.

That's what heavies are about. Making them indestructible juggernauts that require full squads to take down only makes sense if you're going to jack up their suit prices by a factor of 6 and increase the SP required relative to other classes. Otherwise, they don't need anything remotely approaching those sorts of advantages.
