Fuzzy scroll up abit(Not sure its 15%) Thats not the way it works
Since 5 items drop from the cache and there's always 1 item in there I guess it's 20% (I suppose it's reasonable to assume that all items have the same chance of dropping judging by wowhead data). Assuming there's a 20% dropchance, the chance of not getting one in 25 runs is in the 0.75 pct area - or in other words very rare but also (unfortunately) possible.

I'm not sure what you mean by "that's not the way it works" - there's been a lot of conspiracy theories of drop chance being based on class composition in the group, level of equipped items etc etc, but there is really no evidence of this. Basically theres a set chance of the item dropping each instance - it does not depend on class/gear/faction/race/etc, just on chance. The chance of not getting the totem in any given run is 80% (or 85%) and the chance of not getting the totem in 25 runs in a row is very very slim, but it's a possibility (a 0.75 pct one, but never the less a possibility).
