It's interesting to see how this changes will impact the tournaments. What you suggest is one option (the one that I'd also like to see) but probably the least likely.Maybe they'll have to stop punishing AW levels in the tournament and spire forumla so hard when more people are affected by how unfair it is.
The 2 other options are:
1. mid-level players who had much easier tournament because they had less aw levels will suffer the same consequences as those in higher chapters and the tournaments will be more equal for everyone.
2. mid-level players (specially those smart enough to upgrade only the right wonders) will have an even easier time in tournaments because they will have all the advantages of high level AWs (like those players who have been playing a long time) without the added difficulty of techs and expansions the players in higher chapters have. This seems like the most plausible scenario to me.
