The item's description reads, "Attacking to end the invisibility will deal 225 bonus damage to the target, disable their passive abilities, and reduce their damage output. "
Yet I can attest that Break does not disable Pudge's flesh heap passive.
Now, disabling all of Pudge's flesh heap stacks would be pretty huge, at least against a very farmed Pudge. I'm not trying to argue that it should or should not disable any given passive. I am only pointing out that "flesh heap" is classified by the game as a passive ability, and that the Break mechanic does not disable it.
For example, Break doesn't disable Wraith King's ultimate, and I think we can all agree that it shouldn't disable his ultimate. But all the same, Reincarnation is a passive. It is not disabled by break.
Having established that the Break mechanic does not apply to all passives, I've started this thread as an attempt to get some clarity on exactly which passives are vulnerable, and which are not.
So if anyone is absolutely certain that a given passive is not disabled by Break, please post it here... and maybe we can create a semi-comprehensive listing. Wouldn't that be grand!
To jog your collective memory, here's a listing of (hopefully) all of the passives in the game.
Again, it's clear that some of these passive are not disabled by break. Does anyone know which passive ARE disabled?
This newly introduced uncertainty has been pissing me off for quite some time. We can debate forever which passives should and shouldn't be disabled by Break... but atm it seems completely random and abitrary to me. IMHO, if Icefrog doesn't want Break to disable a given passive, then it should be assigned an entirely new category.
