I completely agree with that incentive to play need but there are plenty of players who don't farm or power level (kind of find it to be cheating).
Yeah, but keep in mind, as I cited above, there are plenty of merits and enhancement converters out there. Inflation was in part due to only have a single source of drops at one point (the rare and highly desirable purple drop) and only a single currency largely amassing (INF). Neither are the case.
Luck of the Gambler global recharge could be acquired through:
Lucky drop
200 reward merits
2 alignment merits
32 astral merits
getting lucky with the enhancement converter (that drop from super packs and are purchaseable*)
*Now, someone on paragonwiki was so kind as to breakdown the costs of converters:
10 reward merits + 250,000 inf got 1 converter
1 alignment merit + 2,500,000 inf got 10 converters
3 astral merits + 500,000 inf got 2 converters
1 empyrean merit + 1,250,000 inf got 5 converters
Summarizing, to buy 10 converters will cost about 2.5 million inf out of pocket. What can you do with 10 converters?
3 converters -- change to another IO within the set. pick up the elcheapo level 25 def/end/recharge LOTG and and convert until you get global recharge.
2 converters -- convert any set IO within a category. pickup the elcheapo level 25 defense IO (gift of the ancients anyone?), convert until you get a LoTG, then convert within set until you get global recharge.
1 converter -- convert within rarity. pickup elcheap level 25 IO and convert until you get defense set then use 2 converters to convert within, or convert until you get a LOTG and then convert within set (unless super lucky).
The point is, you won't necessarily have to play the market that aggressively, but there will be folks still willing to pay for instant gratification and marketeers will always profit from them. As stated, I wouldn't tinker with the economy other than maybe raising the inf limit (which I'm sure several people will be willing to accept the challenge of meeting : ' )
Edit:
The first person that tries to sell a LotG global recharge for 100 million may get lucky and sell it, but likely it will sit. And eventually prices will come down. I just don't see recipes necessarily going for the orders of magnitude that they did in the past, considering how conceivable it is to possibly craft 1 if I simply play the game, finishing story arcs and participating in TFs.
