"and if the pass isn't going to include elements of MTX such as skips or putting useful items on the premier track predominantly - then you have yourself a very workable battle-pass that players might actually like. "
We don't have skips and content buffs now, so it should be a "very workable battle-pass that players might actually like" now.
"The suggested balancing, or one that players have a significant amount of agreement over, had better be the same each and every time. It's important for these things to have a consistent enjoyable experience - again if you have to have it in the first place."
The format is likely going to be consistent but the theme will obviously vary. We aren't going to have Hero Pass: Underworld every 3 months. The rewards will be different too. RS3 is not a cookie cutter game that recycles the same content over and over again.
"Why aren't we polling these changes?

"WHY AREN'T YOU POLLING THESE CHANGES?
You've been loud and clear on this topic, and the priority for us now is to fix it. A dev blog is a good compromise in making sure that we're still checking back with you that we're doing the right thing.

"I had a chuckle in an earlier thread of mine when an iron appeared and said they didn't want anything from Hero Pass, because that's what I had thought Ironman was about."
So you realized different IM have different opinions apparently. That's fine, but please read on for what Jagex officially told us:
