New hunter talents in Mists of Pandaria

Few day ago Blizzard has updated the talent page for Mists of Pandaria. I want to talk more about the last 3 talents : Glaive toss, Powershot and Barrage.

Glaive toss:
Veru useful spell with low focus coast .  My opinion is that Glaive toss can be used for both PVP and PVE.

Powershot:
This is something like the Aimed shot ,but with mych more damage. The cooldown is huge but I think that it't fair ,because the damage also is huge.

Barrage:
This is the spell that I dislike the most. It has 40 focus coast and 30 sec cooldown ,but I don't think that it will be better Aoe than the multishot.
