I'm really glad the gloves are gone (too much +dmg far too soon after Muk's).
Regarding the save bracelets, and high-end slot contention in general... broadly I agree that forcing build choices is a good thing for game balance, but because legendary tokens are tough to craft,
1. Only x% of TD players would consider crafting a legendary at all
2. Only y% of TD players would consider crafting two incompatible legendaries for the same classes*
3. I'm not sure how small x is, but I'm pretty sure y is significantly smaller because
4. Nobody wants to craft a legendary and then regret it.
Personally, in practical terms, there's no chance I would ever craft both Luna's and Boaz's; if anything I would choose one to craft and wear it all the time. But if I feel like there's a good chance of an even better bracelet showing up in the next couple of years to outclass these, that frankly makes me less likely to craft either of them (better to just stay with relic or UR than end up regretting a legendary-level "investment" that turns out to be a bad bet). Other players will make this same calculation at different levels, of course, and be just as turned off by relics and URs getting outclassed by new tokens too soon.
In this case I don't think there's much risk of +5 saves outclassing +4 charms, which is good news in terms of not killing the goose that lays the golden egg but bad news in that I expect vanishingly few people would bother to make the +5 saves bracelet. FWIW Endgame's idea of a legendary +saves ring seems somewhat more promising to me since it's not completely incompatible with anything and Pharacus's was a long time ago.
* class-specific legendaries are a special case; I know up front that it's only for one class, so how much I want to make it is determined by how often I play that class and how much will it increase my fun each time I do. I'm making Druegar's this year because that's worth it to me, and I don't care how Druegar's compares with e.g. Benrow's, but it helps that I'm fairly confident there won't be a new neck legendary usable by Cleric next year that I would rather have instead. (If there is I would be super disappointed)
