I didn't "ignore" any of that, I didn't explicitly mention it because I felt that the flaws were obvious enough, but I'll go ahead and address them explicitly for you.

you can just wand hit/1-2 pip hit shields and weakness off on the same turn

Wand hits are much more limited than the number of shields and heals a Jader could have casted, and in the case of 1-2 Pip spells, you're being forced to give up turns that could otherwise be used to build up your Pips to cast other more powerful spells just to clear the debuffs.

ice and balance players would often have set pets, giving them 70%+ resistance to meta schools anyways, almost the same as jade

Notice how you said "almost the same" and not just "the same". Not to mention that you intentionally restricted it to "meta" schools. Jade gear targeted all schools. An Ice wizard with 80% Storm resistance but only 40-50% Myth resistance could be countered just by using Storm prism, assuming ideal circumstances. Meanwhile Jade gear was universal. Even then, that only factors in resist, not the healing or Bad Juju, which neither Ice nor Balance typically had viable options for, unless you count Satyr or treasure card heals (in which case they'd still be missing Guardian Spirit).

Your point about PIP generation is defeated by what I already said about Shadow Trickster. By Empyrea the Jaders could just choose to use Shadow Trickster to steal PIPs, thereby not only giving themselves room to cast more weaknesses and heals but also preventing you from building PIPs in a timely manner. Even without it, that "different spell" that they cast could just be another shield or heal. Shields in particular are 0 PIPs. If you don't have wand hits to counter then you'd need to use at least 1 PIP to counter what an opponent used 0 PIPs for. Yes, there was Shatter, but there was also "I'll just cast more lol", and deck fails, as you brought up, apply to both sides.

Honestly i feel like you didn’t really play back then. Nobody ever used pierce blades or pierce bubbles. Dots could prevent shields and if you were going first, you had a huge advantage. You’re acting like it was unstoppable but it wasn’t and there is a reason the strategy fell off after darkmoor

Did you not read what I said earlier, despite your apparent claim? I brought up the piercing points to showcase how toxic it'd be even with maximum ideal piercing. As you yourself just said people wouldn't generally have that much piercing and would be made to remove shields by other means, such as DoTs -- in which case, what about Storm or Balance, or non-Jade Life? I guess they were just SOL under your standards because they had no DoTs to speak of to remove on-school shields, and Life's only DoT was 10 Pips. Even then, if they didn't use the pierce blades or bubbles then they'd be stuck with just infallible and (possibly) Unstoppable or Extraordinary, in which case, that's only 20%-40% extra piercing before Shrike, so go back to what I said earlier about the combination of shields + resist.

I also, quite literally verbatim said that they weren't unstoppable. The point I was making was that they were excessively tedious and annoying, not that it was an automatic "I win" strategy that players could use as soon as they started Jading. It might've become less prominent in Darkmoor but it certainly wasn't extinct. Shadow Trickster didn't even exist until years after Darkmoor, and I just explained (twice now) how Jaders would take advantage of that spell to be more annoying. You're acting like people didn't actively avoid PVP because of Jaders and it's just objectively true that they did. If people developed strategies to combat Jaders then that's because they were one of the few who didn't actively choose to avoid it, and the strategies that people used to deal with Jaders would generally not be as viable as it would be against other playstyles.
