Support for a mixed solution. The escalating cost of the upgrades is what I am concerned
about. 25 is inconvenient and its only the first one. 50 is a lot. 100
is too much.
I would have wanted to see the first two upgrades cost Pebbles, a
lot of them. Then the third could have been 25 MS, and the fourth could have been 50 MS.
I'm not against upgrades costing MS on principal. It's hard to earn MS right now, but this will not always be the case. It's already getting better slowly and will continue to as more MS are circulating. Give it a few months. Progress in this game does not need to be a speedrun and none of us need these upgrades to play or benefit from Professions. I can afford the expansions, but I'm not buying them. If I had them all now, what would I do with them? Not a lot. There is much more content to come in this (very new) game and I'm happy to wait for its release before being motivated to upgrade. Point is, Crafting isn't the only way to get MS without touching USD; it's not even the best one, the FM is. Given time, MS will be easier to spend on other players' goods and services and spending them on sinks like upgrades won't seem so bad. We will need premium currency sinks like this (different from CA and scrolls) in the future.
"In the future" is the key phrase. I wonder how people would have felt about this if they had staggered the availability of upgrades that cost MS. Just about every new game's premium currency economy is like what we're seeing now, and it always evens out with time. But not everyone has been around for multiple game launches, so they are upset because they don't know it's going to get better on its own. I think the community in general would have taken this system better if the 50 and 100 MS upgrades were made available at a later date when that amount was easier to earn after Pebble expansions were available first.
Anyway, I really want to see both types of currency sinks in Profession upgrades. People seem concerned about spending MS on the upgrades now if they're going to change it Pebbles later, which is valid. But I don't think upgrades need to have a strictly linear cost increase. There could be two upgrade "paths," one for Pebbles and one for MS, for example. A player could do one or both, their choice.
