If Support Gems Are Limited To ONE, We Need More Variety And Less Kiss/Curse

I know there are a couple support gem slots labeled "coming soon" as this is still EA, but going by the kiss/curse theme current supports, I'm not getting my hopes up.

For example; I'm playing a poison build on a 5L and even now I'm having difficulty finding a decent 4th support. I'm trying to plan my 6L/5th support and nothing else is really standing out.

* I was excited for Swift Affliction, but it looks like GGG doesn't want poison using that in PoE 2 when I read the description further.

* Chaos Infusion gives 25 *less* hit dmg, and since poison scales off the hit dmg now it's a massive loss on a physical bow. The slight gain of some flat chaos barely adds anything to the poison value. Also, the tooltip for "damage gained as X" seems to indicate it's not for ailments?
Also, current chaos bows are absolutely terrible for poison. They have 0 base phys and don't appear to roll any kind of flat chaos/inc% chaos mods.

* Moving on to Deadly Poison, a T3 support I finally unlocked. The description is similar to PoE 1, where the trade off in less hit dmg is offset by much more poison dmg. However, in PoE 2 the "more" poison dmg is now "magnitude". Without PoB it's hard to know how good/bad this support is so I can only go off tooltip hit + poison numbers. I loose 25% hit dmg (which scales poison) and the 75% more magnitude only changes the poison/second by about 28-30% more?

*Inspiration and Lifetap support in PoE 2 no longer give any dmg benefits, which is fine I suppose if GGG intends this to go on support skills. However, it does nothing to add on to your main 6L for any kind of dmg benefit.

*Herald of Plague (not a support, I know) does nothing to contribute to our poison magnitude or even duration. It feels like such a weak option compared to everything else we can use our limited spirit on to increase our dmg or defenses.
Most of the poison skills come with some kind of built-in AoE too, making HoP less desirable.

I'm not sure how it is for direct dmg/hit builds, but looks like cold support gems have decent variety to choose from.
Other people in Global Chat have mentioned similar issues while making their poison builds, but again, can't really speak for all the other elements/dmg types yet.

Anyway, this has been some of my frustrations and disappointment with making a poison build, especially my main 6L.
