I've played about 40 minutes and here's my review:
Features: Everything seems well balanced for a 100x server, the nobless option that they choose can be different in a way, it's not anything new because we all know it from the rebirth system, the events are pretty awesome, there's not too many but to be honest, people do not join that much in events now a days, unless the reward it's pretty big or useful like they did in here, if you want to enchant your items with blessed scrolls or get other goodies, you'll need to join the events.
NPC's: You have to join and see with your own eyes, the admin did a pretty good job placing them where the players wouldn't feel the need to ask themselfs, where's that NPC? And start shouting for no reason.
Zones: The GK provides pretty nice locations to level up and do everything we need to. The farming zones were built in a way that we can all farm and pvp at the same time because there's enough space for everything, my favorite one is 4S because there's a Raid which we have to fight our way through to get it, that's a major plus for me unless the server doesn't get the population it needs.
Augments: There isn't which brings more balance in a way, the game featured it, sure, some people can make it work, others can't so not having it at all gives us a little more of a C4 experience in this server.
PVP Arena: Another feature that you don't see every day, you'll need to be 80 to get inside and as you keep getting kills, you'll get crystals which can be exchanged for useful items in the PVP Arena Shop.
Cons: The only con that I might have to point out is the mana potions, since it's 100x people will get equiped fast enough and want to pvp as soon as they can, so having this much delay on the pots will simply make the mages unplayable since it's fast pvp. I do understand that the main reason is the healers so they can't spam skills just like that but I'd rather change the skill reuse than the mana pots.
Pros: Protection, the main feature that a server can have these days and they have it, or at least claim that they do. VIP system, isn't unbalanced and won't make you a Power Ranger so to say, so, that's really nice to have if you can afford it.
I'll keep updating it if I see something new, 40 minutes sometimes isn't good enough.
