I dueled last nite. I could start Selo's while rooted but it did nothing.
No pulse, no message, no ungreying of song buttons. Zip, zilch, nada. Only
while already playing it when rooted did it break it on a pulse. A
reasonable compromise in my opinion, but they will probably say it is a bug
and nerf it again.

Actually, I was dueling a wizard friend of mine--he
was 30 and I was 26 level. I broke root with selo's
everytime on a pulse. I even wouldn't run it
constantly and I could start it up and break the root
on the first pulse. Haven't checked on mobs.
Usually, the ones that root me lately can kill me in 3
casts anyway, so I don't really have a good way to
test.
