How Big Is The Skill Tree System?

I've seen games have an skill tree system all the time in MMORPG, But how big its gonna be? Also will there be a Secondary set over next evolution in all classes?

There is no skill tree. Skills are learned individually through discovery. However, there is a talent tree.
You can read about both here.

The game will have more than 400 skills and 40 of them are buffs and debuffs

@muker Correction: There are over 400 skills and 40 unique status effects.

Can't wait to see all +400 skills...

Are all the status effects detrimental (i.e. slow, stun, bleed, susceptible, etc.) or are there some positive/mixed effects like invisible, brave, tough, immune, etc?

@kellewic I don't know.
