Also use proper sales techniques. ‘We did it like our competitors do and realized this doesn’t work for us’.
Nah… EHG did it half-assed without realizing why the methods of competitors actually work and that’s a big reason as to why it doesn’t work… not for them… but overall.
The supporter packs from GGG provide the full range of points related to the cost of the pack. That means if you buy a 30€ pack you get 30€ points. The MTX is the cream on top basically.
This way people look at it and say ‘what a deal!’, buying in even if the MTX is only barely something they personally want… after all you still got the points and can use em to buy MTX you actually want a lot and got the stuff on top!
And the ‘it looks like ass’ part, absolutely so.
I still remember the absolute baller looking supporter pack back when Abyss came out in PoE 1, that one was amazing! And what do we have here at LE? A slot back attachment… ok, fine. A toucan… ok, fine. An axe and a sceptre skins.
Yay? The chance someone wants those specific things is not all too high now, is it?
But a fair comparison is only available when we look at what the 30€ and 60€ supporter packs provide comparatively.
LE:
30€:
150 points (15€ value, so you basically pay 15€ for the MTX)
The included MTX are: 2 back attachments (wonderful, so we get double slotted stuff… great…), a pet, a portal, an axe skin, a scepter skin, a one-handed skin, one armor, a evade effect and a footprint effect.
The footprints by the way are absolute ass. The cloak is mid, as are the weapon skins.
60€:
300 points (so now the MTX costs 30€ already)
Another cape, another portal, a two-handed staff, another armor, another evade, another footprint for the 40 upgrade
And then another back attachment, another portal, another one-handed sword (now we even double up on weapon skins!), 2 more pets (which makes a total of 3, so 1 unusable), a shield skin, another armor, another evade and another footprint.
It’s plainly spoken shit, utter and absolute shit. Stuff is either extremely specific (weapon skins being for weapon type rather then generic melee/caster/ranged ones)
The result is you pay 15 or 30€ and have to like the specific stuff in those packs to have gotten the value out of em.
Now for PoE:
30€:
300 points (which means all MTX is free on top, you already got your value. Kinda… ya know… supporting the company with it rather then simply buying points normally)
The extended digital soundtrack
a character effect
a weapon effect.
Now… that doesn’t look like much, LE’s looks like it provides vastly more. But for a price-tag of effectively ‘0’ it’s quite the massive value, right? 
60€:
600 points (So still the MTX is absolutely free)
A full armor pack with hood and helmet for small variety of choice… and a pet! Also the pet looks really nice. Animated, has a ongoing effect, despite that being one of the worse ones overall available.
Also another thing EHG utterly failed to provide which is a massive money making machine for GGG in comparison: A social space you own. In PoE it’s the hideout… and that has decorations. People buy decoration stuff like mad, after all it’s a massive aspect to show off your stuff to other people. LE lacks basically all methods to make that a actual thing. It would’ve sufficed to make the mechanic which PoE 2 has (buying stuff remotely and then simply picking it up at the Hideout) to make that a valuable and viable thing.
But nah… they ignored massive incentives and now they’re all pikachu faced wondering why their MTX fail.
