Tinfoil Hattery?
 

Over the last week or so I have noticed my 58 shaman, who i rot with daily while leveling in KC, has been interrupted while casting SIGNIFICANTLY more. This is almost always while trying to cast Paralyzing Earth to continue rotting. I used to get interrupted trying to channel maybe 1/5 attempts while face-tanking 1-2 mobs (normally sentries and guardians). Now its easily 50/50 or worse. Its almost as if mob knockback was ninja-adjusted?

Any others noticed this? It has been significant to me soloing, having to adjust by over rooting now, but nothing that is game breaking.
