Nifflheim came before the transcendent patch. He does exist. All I need to know is if Ice Pick came before the trans patch or not.
As for selling equipments, that sounds like custom retarded crap to me. If you want gears then you have a work twords it. In the time you make the money to buy the cards/equipments anyways, you could have already hunted the card. It just makes no sense to me to be selling cards and equipments through NPCs. .10% drop rate on cards is not low at all. A GRIND to get cards? Hardly. Yes, I have played on low rate servers and to be honest, it doesn't take long at all. Plus, most cards you need for WoE/PvP are easy to kill monsters. Most characters can easily kill them so its not even a struggle to get them. Boring? Maybe, but its just something that has to be done if you want to WoE/PvP. Not everything can be fun. Although, many people find it find to hunt/level, I guess you don't.
Imbalance? A person who spends more time collecting supplies/gears for WoE technically deserves to be better in WoE/PvP than someone who doesn't. They WORKED (not really as you just click) twords it. The thing is, I didn't agree with this for Transcendent class as I remember on iRO it was so much more team based than Hey Look At Me I Can One Shot You Because I Have Retarded Skills. Of course Monks had Asura Strike but there was something called Hide. Sure, they had Ruwach but sometimes you just have to admit defeat. Plus, all their SP is drained anyways and a full spirit Monk is easy to take down anyways with their s*** VIT.
Bot driven economy? Uhh, no? Its 10x drops it is ridiculously easy to get things, no joke. Ask everyone who plays other 10x rates servers. Its very hard to have an "economy" on a private server anyways, it just doesn't work. Of course, botting would not be allowed and thus they would be banned. Sure a few might sneak by when no one is online and they might get a few cards but hey, nothing can be perfect can it. Just ban and move on.
Sure, on official servers you are able to buy gear. Thats just the way it is, because there are bots (that the GMs give less than s*** about since most are paying customers) and players that have found the items. If you think about it thats how people make money too. On a server I played in the past, friends and I hunted equipments and cards to make money. Plus, have you ever heard of haggling? You can always cut a deal with another person if you don't want to buy their 20m Thara Frog Card when there are 10 people on the server. Really, it works. And if they don't agree, make money to buy it, just like you suggested, or even hunt it (lulz).
I want the server to be
close to official, not exactly be it.
on your server (which isn't going to be very popular)
I'm sure there are servers that sell equipments, like how you suggested. I suggest you play on those? (They aren't that popular)
Thanks for the suggestion, anyways. Server is coming along great.
