Hopeling

Yes, the tohit bonus on the proc is very large. If it's too strong and they don't want to reduce the proc chance (for whatever reason), reducing the size of the hit and damage buff would also be a possibility. Although, really, I'm not convinced a high-but-not-guaranteed chance for a 5-second buff from a Unique rare proc in a longish-recharge power will actually need nerfing. It's certainly a huge improvement over the current 5% version, but the current proc is garbage.
No, the Gaussian proc's duration is five seconds (well, 5.25s to be precise. OTOH, part of that might be wasted by overlapping the power's cast time, not sure). The Rage crash is always ten seconds, whether stacked or not, but double Rage means crashing twice as often.

Since the i24 proc changes have not even started beta testing yet, I wouldn't be too confident that any part of it won't change.

Five seconds, actually.

Unless they change their mind about the Gaussian proc specifically between now and i24 (which is possible, but so far we have no indication that they will), this is not just being considered, it's announced and already underway. The Attuned version of the Gaussian set has been on beta for some time, awaiting release, and the proc is still sitting at 1 PPM.

The formula certainly can accept decimals (Performance Shifter is 1.5 PPM, purple damage procs are 4.5, and almost every proc will have a non-whole-number PPM come i24), and the cap is 90%.

I know. Which is what makes it so bizarre that BrandX chose to harp on the one instance of this that does happen via time travel, and in a way that is consistent, rather than any of the examples that are inconsistent and actually comparable.

Because traveling back in time is not the same as taking the tram to Independence Port?

We ran Statesman and Sister Psyche before their deaths. Then they died. And we still had run the TFs before their deaths. That's why we still have Statesman's Pal and Sister Psyche's Comrade. But we can't run the TFs again AFTER their deaths. Because they're dead. We can run Sister Psyche's TF via Ouroboros, by traveling back to before she died.

Some comfort that is to my BS/Inv, especially since he was created long before Shield even existed

As far as I'm aware, SS hasn't had any development looks at all in years. The last dev comment that I recall on the topic was from I think Castle (?), saying something to the effect of "If you like Super Strength as it is, don't ask me to look at Super Strength. The set will be changed drastically if I ever look at it."

That's true, but the benefit is not so small that 1-2 slots in Hover is a high price for it.

IMO, the best synergy TW can get from a secondary is help with endurance, and EA provides that in spades, while SR and Dark provide no help at all. Defensive Sweep is OK, but not the main thing you need to build around, and can be skipped entirely if desired.

Elec Armor would be a fine choice too, for basically the same reason, as long as you don't mind not having a taunt aura.

That's not silly at all. That's the most useful thing for it to display. After all, it wouldn't be a very useful statistic if it just showed 5% all the time.

The health per second numbers are not wrong, and they are the best way to look at regeneration - unless you're talking about very short timescales, getting a tick of 150 every 12 seconds is just as good as getting a tick of 75 every 6 seconds, so it's useful to be able to see that either is the same amount of health per second.

Base regen isn't always 5%. Regeneration, base or otherwise, always happens in ticks of 5%, but the rate at which those ticks happen makes all the difference. Regeneration is a rate - health per second - and a rate is a relationship between two things, so it depends on both the amount healed (dependent on max hp) AND how frequently that happens (dependent on regen buffs).
