Ok, so after playing for a few days, here's my feedback.
The server stability is great, less to no lag. Good job on that. I don't know where the server's location is but my suggestion would be Europe.
Giving the players a lot of exp items very early on and not removing the Quest cap will cause frustration. You out level everything you encounter by 20 levels, but you can't increase your level because of the oldschool quest cap. It feels like the player does not accomplish anything. Here's what you need to do:
A) Remove the Quest cap completely, only leave the upgrade quests (120-130)
B) Don't give so much free exp in the early levels.
C) Do both, players can do whatever they want from the get go but they don't rush to lvl 120 in minutes.
The addition of a chance to aquire several Platinum Coins through Medici broke the economy. New players will suffer tremendously. People don't just trade horrendous sums for minor things, no they already start trading with full stacks of platinum coins. How can a new player even start in that enviroment?
A) Remove those coins from the medici boxes completely.
B) Include the Box opening cap, so that players wont open 100k boxes a day and have their inventory just bursting with those stupid things.
Some little notes:
The ability to get Atlas Ore that easy seems a bit wrong, in the lategame when it comes to gearing, it is one of, if not, the most important item in the game.
If you remove the Coins from the Medici boxes, maybe add them as a Division 1 reward in Free League, since we don't have the Grand Championship yet. Or give it to people who compete in the Weekly.
The Quest item droprate is ridiculously low, i mean it's insane. Multiple times i was grinding for quest items (one quest took me a bit more than 30 minutes). Players that like to do the quests won't be staying long on this server. Or players who need to do them because of the quest cap. Players with no patience will say "Fuck it i'll go back to Server A or B."
All in all the server is stable and has no bugs. The economy is fucked up really bad and the combination of that and the existing quest cap makes it a horrible new player experience.
That's all of what i can think of now. I'll add things later on.
EDIT:
You could also (I don't know if that's possible) move all the class trainers to a stationary point (Rome). Like Cai Lun near the Sea Palace/Shanghai but with all the crafting artisans leveling possibilities, not only until lvl 10. It's just a minor fix to the stupid articial gameplay prolonging tactics of NDoors/Nexon.
