TERA fan but not lucky enough to score an invite to En Masse Entertainment's recent Community Play Event (CPE), you can take heart in the fact that the company has released some information pertaining to all the players who did attend. We know, there's the potential for some salt in the wound here, but En Masse's Jon Tuite nonetheless has some interesting factoids relating to character races, classes, leveling trends, and many other data points.
It seems that Castanics were the most popular race during the recent CPE, and humanoid races in general accounted for a whopping 68% of all characters. Tuite also points out that the Baraka race was the least popular (7% of the population) and postulates that the lack of a female version could be the culprit.
In terms of class and party dynamics, the CPE data aren't far removed from your average fantasy MMO (i.e., there were a plethora of DPS types, fewer tanks, and even fewer healers). These stats are the tip of the proverbial iceberg, and you can indulge in more number-crunching at the official TERA website.
