How is power technician node supposed to work?
I have been having mixed successes with this node. My question is the interaction between well-timed block with armor up and the fury gain.
I have tried warlock, guillotine 2099 and guardian. On parry I would power drain most of the time (but for some reason sometimes it fails). But even if the "power drain" text pops up, I do not always get a fury. It appears that it is much harder to get the fury at the beginning of the fight (maybe 1 in 3 or 4 furies) but as the fight goes on I may be getting them a lot faster. But this is not consistent in all fights, and some fights I get them right away on the initial parry and keep ramping up quickly. I am not fighting any champs with ability accuracy reduction as far as I can tell. e.g. Luke Cage in this month's 1.1.
On the other hand, other types of power drain seem to always work. e.g. Guillotine 2099 sp1, Guardian 4th light attack, etc. Red Skull also seems to reliability gain 2 furies every time I parry probably because of power technician and his normal drain.
Is this a bug or is there some explanation to this?
