The Soundburst SLA wasn't hitting anything. This should be a fix/buff.
The DCs will be better, but the cool down will be 20s now. So it'll land, but with such a long cool down will feel meh.
At lower levels, the DC didn't matter, because the sonic damage + magical ambush killed almost everything in one shot. But a 20 second cooldown versus 8 seconds is going to make me reconsider the next time I have to level up. I'm almost level 20, so Sound Burst isn't as powerful as it used to be, but I was using it as part of my AOE spells I cycle through when fighting groups of enemies.
I guess I'll be looking for a different spell to put on my bar. Maybe I'll use the Chain Missile SLA followed by the Chain Missile spell. It'll cost more mana and the AOE is going to suck in comparison though...
