I know we need to wait, I have no issues with that, but by the same token, I highly recommend them looking at this portion of update 249 in conjunction with the New Player Experience:
Solo character skill trees:
We have made major changes to the Skill cap and progression system in the game.
To allow a solo player to craft all items we’ve updated the skill tree to allow characters to unlock all independent skills.
The skill cap is now 359 Skill Points.
We have removed alternative selection links for many linked Epic Skills. These changes are to allow players the freedom to use a single character for all areas of the game. However we have retained Epic links to create DPS, Tank or Healer characters in combat.
Players will receive 2 Skill Points per level until level 180.
Skill points are now no longer shared between skill pages. Meaning the player can spend their max points in each page.
XP required per level continues to increase between level 50 and level 180
