You would fill the resolve of enemies even if you don't want to.
you would knock targets out of range of melee allies (smash).
combinding major damge abilities with ccs is always a double edged sword.
(just imagine huttball and a clueless sorc useing thundering blast on the ballcarrier tank , making him unpullable and and ccable before he even passed the first fire)
Doesn't this apply to snipers already? :S
Then again.. there are like x10 more Sorcs than Sniper on ToFN
