My linkshell had its latest attempt against AV last night. We were trying for minimal locks against AV, but we had a lot of troubles which caused us to never get him below 90%. There are 2 interesting things I noticed about our fight however. This is the second fight we've had against him where he used benediction after we broke regen, and the second time I noticed his regen returning after bene. It might not be full strength regen, but we were able to get him down to 95% hp with tier 1 and 2 nukes once regen broke. After benediction, we couldn't get him below 98% for longer than a second until I told BLMs to go all out on him. They got him down to 95% at one point, but he was back up to 99% in under 2 minutes.
The second interesting thing is PURE VOODOO and I make no claims that this will turn out to be anything worthwhile. However, during our entire fight, AV didn't use hundred fists a single time, and we had about 70 minutes of active fight time against him. There are 2 possible explanations for this. The first and most likely is that it was simply luck of the draw, and there's no coincidence at all. However, we had a monk in the alliance the entire fight simply waiting to lock hundred fists. She had active hate, stayed within 20' of AV, and was wearing faith torque 100% of the time.
I sincerely doubt this was a designed way to weaken AV, but it should be easy enough to test as long as I can convince my LS leader to give me another shot at AV
This should however give you a good idea of how difficult a minimal lock attempt against AV can be. If AV can simply choose not to use benediction for over 70 minutes of active time, it's very easy for you to get screwed later in the fight.
