Ah I was waiting for the Primaclone to be brought up. To begin with Primaclone was never a 'Gowen' tech it was a multisphere tech. Remove the Falkow influence from it and Primaclone is impossible is it not? But lets just say we acknowledge that factor let us continue with the conversation
Primaclone had no viable counter for any sphere outside of falkow that could backlash. Now I can say this with certainty because around that time lets count the number of grimbane or grim resistant units each sphere had eh? Before set 7 there were a grand total of 4 units that could effectively grimbane. 2 of which were falkow being fellana and Mage Knight of Regus and the third being Dargon who required a condition of being night. and notice not a single grim immune unit.
Fruit was the single most unreliable counter to this mechanic, for a number of reasons, one you could only effect 2 units and it was fifty/fifty mix up on if fruit would even effect you units before the cyclone. So to have any chance of winning one would be forced to play big file, which I don't believe is healthy for a games growth. But much in the same way your opinion and mine differ i may be wrong.
Pixies were the direct opposite in terms of playing or rather not playing. While primaclone almost always ended with the opponent having thier entire field returned to their hand. I saw more than a couple of pixy games where the opposite play only managed to play a unit with the character and level 4 lock when they were on their last SS. Certainly that has to be healthy for the game environment right?
I will give you that the nerf to Rhino action, Bringers Open and jacks start being changed to an auto probably aren't need anymore and they'd be alright if we changed them back to how they orginally were. Though having a unit that revive itself having natural defense is probably a bad thing. its not like you can't use a dyrad on him or anything as he is now. You also make it sound as if Pixies can't lock players out at all. Its just you can't rob a player of over 6 turns without play.
Each sphere has had its share of Nerf cards when things were getting bad for them, or does nobody remember the Laps Kaldro nerfs/ Miffy and Veraalt? How about Ruuca or Serpent and elite fencer?
But I can't see an excuse for why a level 5 unit or higher should be returned as an SS for no negative sp penalty when all other SS have that same vice. Returns all come with a trade off so why should that be an exception? Just because gowen has the easiest access to it doesn't make it valid. If said by privy of Refess having sunbeam cage that the strategist SS should have no -1 sp cost or all the agi based one didn't need to have that same sp cost reduction.
I have admitted multiple time gowen has been left a bit behind but you make it sound like they've been the only ones to get Lemons. There have been less then useful cards in all sphere introduced. The honest truth is they have viable files just not steamrollers like they use
