It is about time to remove the useless perpetuation system.
It has already been proven for countless years that a zero perpetuation carbuncle is not effecting game balance. A zero perpetuation Fenrir or Garuda does not effect game balance. And now with abyssea we know that a zero perpetuation ANY avatar, is not breaking balance. Which means the only reason the system is still there, is because someone thinks Summoners should have less fun than other jobs. That is the only purpose, making the job less popular. A useless design, considering the job isn't even popular to begin with.
I'm well aware the amount of gear that would need re-designing if the perpetuation was removed, but I think you are only getting into a worse situation the longer you postpone it. It didn't make sense to begin with that Summoners where the only job equipping gear to offset a design flaw. You never pushed PUPs into wearing "-1 min recast on activate" gear full time, but you instead added a 1 min base JA to call a new one on death. Stop forcing Summoners to collect hundreds of armors to fix YOUR flaws with the job. Perpetuation is not balance related, so all it does is prevent you from actually using the job.
As a side note, you've completely forgotten to give spirits new spells BUT remembered to increase perpetuation. So I'm supposed to pay 7 MP per tick extra for the exact same results? Why not force a BLM to pay 100 MP extra for the same Thunder IV but renamed Thunder V and see if they'll react. Only reason you aren't spammed about this flaw is because people already gave up on your lack of responses years ago.
Until you fix this, you'll see me enjoy Abyssea and not care at all for the rest of the game. Take it as a hint that the only thing you ever did right since 2001, was Abyssea.
