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.
This sums up my feelings so perfectly. Bravo....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.
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.
