Frost Bomb will now detonate after 4 seconds (was 6 seconds), and the damage it deals to other players has been reduced by 20%.
If the Fire Blast glyph change wasn't enough to force me into another direction for PVP, I'm pretty sure I'm headed to respec fire right now.
Although, trying out Frost with one of the other bomb spells might be intriguing.
Any thoughts from the community?
