At ChangYou New Game Summit 2014, 17173 had an interview with Bless Online's producer Han Jaega. According to Han, PC requirements of Bless Online won't be higher than Blade & Soul.
There are two factions in Bless Online totally which are Union and Hieron and ten races including Amistad, Aqua Elf, Iblis, Pantera, Siren, Fedayin, Habichts, Lupus, Mascu, and Sylvan Elf. The core feature of Bless Online is realm vs. realm combat. The strongholds in Bless Online world are interactive with players. When a player reached a certain level, he or she will affect the level and status of the stronghold and the rewards and buff he or she receives from the stronghold will change too.

This guide explains the formula you should look to follow, so you don't have to waste time on things like learning the UI or knowing exactly how to get EXP. The general formula for efficiently leveling to 45 is as follows.

An initial look at the Bless Online creature taming system is provided by the devs, showing off some of the hundreds of critters awaiting capture.
Looks like another interesting game and here is the new trailer for Bless Online.
