Avatar is a major buff, 24 second duration, +20% damage is no joke, and that root breaker is nice. Pity about the nerf though.
Storm Bolt has neat damage, solid cd, and that stun can be a life saver more often than not, and very useful to help you catch all them kite comedians.
So what do you think? Avatar or Storm Bolt? (for pvp purposes)
