So how many players didn't complete the tutorial is the real question?
82 out of how many completed the tutorial?
You have 175 accounts currently on your server, lets say hypothetically there is only 1 player per account, that means if 82 players completed the tutorial out of 175 that is little less than 50% of the player-base.
Although if you look at your active players in the past 4 days there is only 10 total and since you have 4 vocations that I know of, these 10 players could be from 3 accounts if the players were allowed to make 1 of each vocation per account.
If your going to prove your point with numbers you have to provide all the values not just the one's that support your statement.
Anyway a tutorial is supposed to be a summary of the inner workings of the game, it is suppose to prepare the player for the gaming world, every aspect of the tutorial should build on the next.
I tried your tutorial some time ago and although I was disappointed with the creature I had to kill, I never used any of the skills I acquired prior to the encounter with the creature.
Just looted some items based on my vocation and then ran down a corridor of fire only to meet with a creature that didn't want to die or if it did die i ran too far away only to come back to having to try to defeat this creature yet again.
Needless to say I lost interest pretty quickly, this is something you should avoid if you want your server to be successful.
