Let's be honest though, FV is not a poor server and the cost of everything is so much higher than any other server. Want to buy that uber breastplate at lvl 75 that would be 1k pp on a normal server? Be prepared to pay 5m pp on FV.
Exaggeration? Possibly...but you get the gist. FV is a financial commitment IMHO.
I am going to disagree with you here partially. Sure FV has more platinum floating around, however pretty much all gear is less expensive than on a regular server.
FV costs less - unless you really are committed to have the best and latest.
However the best on a regular server will simply be unobtainable while on FV it is an expensive but possible proposition.
What items are significantly more on FV than on a regular server?
Krono goes for about 2x on FV than on any other server, but it goes so much further.
FV is generally less expensive on items that are droppable on other servers and of course offers much wider(and cheaper!) selection of alternative items.
Just as an exercise do search for some general slot item on a busy regular server and on FV.
On random I tried 110-120 necro ears with effects on Xegony and Firiona Vie:
Not only did Firiona Vie have much wider selection, the few droppable ears that Xegony did have were same or more expensive than FV.
I think only Chilling Stud was roughly the same price, the rest of ears were cheaper on FV, because better more plentiful alternatives are available.
Sure technically cheap 5-10k prestige ears you could get by looking for rots on a regular server, but that would take much more time than simply hitting baz.
I hazard a guess that the situation is the same for pretty much all slots.
The most extreme situation will be pet focus gear.
On FV you can pick up EM30 and EM31 ears for a few Krono, on a regular server you will be paying 15 Kronos for old EM29 ears.
The exception on FV might be some weird collectibles or wrapped items.
