On the PTS, the platinum cost for the 5th tier of upgrades to all dimensions is exorbitant.
A dimension that costs 600p to buy and upgrade to 1000 items now costs 3,875p to double the item count? With no alternative method of being able to do so, such as in-store credits?
As a deeply addicted dimensioneer, these prices are very distressing. I've read posts about excess plat needing to be drained from the economy, but I can safely say that 90% of the people I know, particularly those who build--constantly--do not have these deep reserves of platinum. We're already spending it, time and time again, with grinding and farming in between to get items and farm the money for the next build. There is no excess.
I've read posts that there will be a 15% boost to platinum gains earned through questing and grinding. Fair enough. 15% will not equate to an increase that substantial in costs.
Some solutions: Tier the final upgrade. Have the final price remain unchanged, but additional tiers will make the grind less painful and the goal more attainable (because when goals are unattainable, they're not goals, they're pipe dreams).
Make the final upgrade available through credits. I, for one, would be willing to pay a reasonable amount of credits for the final tier.
Reduce the price, significantly. Between the platinum costs of new items (which by themselves almost caused me to suffer an aneurysm from sticker shock) and the costs of the final upgrade...Bluntly put, I can't afford it, and neither can several other people I know. The dimensioneers who throw up build after build are generally not the people sitting on piles of platinum, as has been stated many, many times.
I prefer to earn things in game, I don't want things handed to me, I understand farming and grinding to pay for things, but this is a point where farming and grinding would become all I ever did, and that isn't fun.
