Thorn Wall Vs Shatterring Scream

[eagleswords]

I would say Avian Scream

Pros:
Stun everyone around you (Range like mage and archer deals NO damage to you)
Damage HIGH "100 +"
Lower mana cost

Cons:
Close range
-----------------------------------------------------------------------------
Thorn Wall

CONS:
Stop everyone around you BUT they still can do damage
High mana cost
VERY little damage done like "16" ??
