So what do these do? What are their properties?
I am tempted by this starter pack b/c the mist tanks, slots, and these items makes it a good deal (obviously, and that is the point of it) but the real deal maker / breaker I think is gonna come to these...
Are these items worth spending cash for? Or will I be better suited to keep on my demo and gunslinger suits?
The 7,500 is what you're buying for the $20. The rest is supposed to be gravy.
But if you insist on valuing the rest:
The items are 1* and worth nothing in the long run.
Not sure what the artifact is.... I'm going to assume it's worth nothing as well.
The 5 mist tanks = 500 energy
2 of each upgrade slots = 800 energy
Assuming you have a use for it all, that's an extra 1,300.
So you will have bought 8.8K of energy for $20 (or 441.1 energy per $1) which is a better "value" than the 20K CE for $50 (or 400.4 energy per $1.)
Are the items still a deal breaker/maker?
EDIT: I completely forgot about the heater amplifier (which sells for 800CE)
But given the majority of people's reaction to it, let's value it at 0 CE since you wouldn't have a "use" for it since everyone values it as nothing. =)
If you were going to use it, I would recommend using it when you have more gear and intend to make a lot of runs in two days at a lower tier.
It would be wasteful for someone just starting out since early equipment is relatively quick to heat up.
EDIT #2: If you go through the website's energy purchase portal, you can see a banner with both items.
