"The Alpha" is actually a gimmick by Trion.
If you consider a live Korean server 1.2 version is Alpha, then thats just you.
Trion wanted to see how many players are interested to purchase the Alpha Access. Therefore, they created the scheme of buy to play alpha access.
If in case, TRUE ALPHA is Heroes of the Storm (by Blizzard) in which players are selected to participate, not to buy access.
Now back to the game.
The game is very huge, a lot of stuff to do.
Mainly focusing on "Group", so if you're a solo player, you'll have hard time. But that does not mean its not soloable. Just that you get into hard times.
Game focuses on Labor Points, which is like Fatigue in Dragon Nest.
No Labor point, cant do shit in game.
