There is nothing more annoying then being double stunned, get your resolve bar to full then BAMMM root! For a melee this can be pretty bad then stun again when your resolve starts to drop.
SO YES, root should affect resolve, its just silly that it doesnt right now, we can argue how much, wether its 100 per second or 50, the main thing is that root is soo easily abused right now, you can call it strategy but frankly its just death for most melees.
