What's the maximum number of Determination buff stack you've seen?

Never made it past 4 but I don't really go into LFR until it's been out for a few weeks. Don't have time for the wipes and it's not really that great of gear anyway.

10 on Nazgrim, yeah it was bad, idiots attacking him during defensive stance, and not killing adds.

Probably went through 50+ people also, with people dropping group and new people joining.

i think like 7 on lei shen and durumu. mostly people failing at the maze.. and on lei shen some tanks were pulling then leaving the raid after 2 mins.

7 I think on Garalon back in the day.

6-7 on durumu

Where is this mystical source saying it stacks only to 10?

Could be this: http://www.darklegacycomics.com/385.html
or comments on wowhead: http://www.wowhead.com/spell=139068/...ation#comments <-- no source listed

Couldn't find any official sources that state maximum number of stacks.

had 6 stack on shamans, on my alt. before we downed it barely.

we needed 3 stacks before nazgrim finally went down. (on 2 stacks we just hit the enrage with about 1-2% left.)

7 on Durumu first or second week
