Why are the Mundus Stones available as Crown only for 4,000 Crowns? All other services-based items such as crafting stations and target dummies have the option of being attained with Writ Vouchers. Crown-only Mundus Stones very inconsistent to the current system and look like a blatant cash grab. There are currently 13 Mundus Stones, and obtaining all for your home (or guild home) will cost 52,000 Crowns, which is $400 after tax!
Having a Mundus Stone available in your home can save you maybe 30 seconds on the very rare occasion you actually need to use it (I haven't needed to use one in 6 months myself). However, having it available in the writ voucher vendor (perhaps as an Attunable Mundus Stone) will create a goal for players to work towards, meaning people will have additional reasons to play the game, and the Crown option will be a lot less off-putting.
In other words, would I ever spend $43 on a single Mundus stone that may be obsolete in 2 months due to a build nerf? Hell no. Would I have additional reason log in daily and do writs if I could get them on the vendor? Hell yes.
The Mundus Stone needs to be added to the writ voucher vendor. Currently, 4,000 Crowns as the only way to obtain one is ridiculous.
