Yes, the blood pact usage >> Avatar's Favour reset thing is insane. I'm fairly sure most summoners don't know about any drawbacks to the job ability, to be honest - so many seem to full time it for the perpetuation reduction.

With regards to the accuracy penalty, I don't think more penalties are the way forward here. Personally I already rage enough when my blood pacts deal <500 damage so this would be particularly irritating for me. Advovating avatar's favour as a support stance with reductions to offense is ostensibly fine (SE's glass-eatingly awful implementation notwithstanding) but the benefit and flexiblity must be very much there to compensate for that reduction in offense; I would say that before discussing specifics re: penalties a re-worked set of bonuses should be drawn up first.

...the mechanics behind Avatar's Favor, which seem relevant when talking about Summoner buffs, are still as weird and off-putting as somebody's grandpa in butt-less rubber pants.
This sums up my feelings so perfectly. Bravo.

As a side note, I think it would be worth keeping things as on topic as possible with regards to Ward effects. General SMN discussion is always a great idea, but with Okipuit specifically focusing on Wards I think this is the optimal time to get our thoughts on them across once and for all, and get them sorted out.
