[10] Plauge injection on Grobb Bugged?

[Ruex]

My guild was running Naxx10 last night, and i know from our previous experiences in there, grobb would get injection happy at about ~20% health hitting people more often then every 20secs or there about.

But last night we had it that grobb was at about 40%health and was hitting folks every 5 secs with plague injection (as per my combat log), and it was just insane.we ended up wiping after 7mins or so, but i know he has a enrage on normal that is 12mins there about.

Has any one else had this problem, or know if there was a change to his injection timing?
Thanks.

I haven't seen this, but they did increase the overall pace of the fight since beta and 40-man...
