I wouldn't say this set is dragons maze level suckage quite yet. Honestly outside of the supplemental products the standard sets have been been gradually decreasing the power level and complexity for no other reason than NEW PLAYERS.
No, c'mon, I'm not going to comment on quality, but this is absurd. KTK and BFZ are two of the more complex blocks ever (and almost certainly the second most complex set of two consecutive blocks, following Time Spiral -> Lorwyn.) SOI is a step down from there but it's still got DFCs and madness and a bunch of other weird stuff. Standard decks, even the ones people don't like, are frequently more intricate and have more decision points than many previous eras of Standard. There's just no case to be made that if there's a problem with current set design it's that these sets are
too simple.
I think the question is less "is this new" and more "is this interesting". Investigate was an awesome mechanic to play with last set. Oath of the Gatewatch was so powerful it broke Modern for a bit. I don't think you can really draw a straight line of "suckage" from the past to the present be it along complexity or power level axes.
Right, I mean, for me, the last few years go from RTR (two solid large sets with an astonishingly bad small set) to Theros (a solid B+/A- big set with a D-rating small set followed by like a B-) to KTK (an all-time-great first set, a nifty but awkward small set, and a kind of boring big set that everyone thought was weak but then turned out to be full of power cards) to BFZ (worst big set of the modern era, then as close as you can get to salvaging the block with the middle set) to SOI (the first really successful return set to start, and then we're still seeing with EMN.) There are good and bad sets across that whole list, and my two favorites of that time period (KTK and SOI) are in the last two years. There's no clear arc of power level; we're actually coming off a local maximum in complexity. Most trendlines are historically pretty tough to fit to Magic set releases.
Ian Duke and Erik Lauer have the killer instinct you need for a lead developer..
Kaladesh is Maro and Shawn Main co-leading design with Ian and Erik co-leading development, which is (absent tricking Garfield into working on another set) probably the closest to a dream team you can get in current Magic R&D.
With EMN, I'm a little surprised just because Sam Stoddard a) is generally pretty sharp in his column and on Twitter (unlike LaPille whose bad opinions were on full display everywhere) and b) had his previous lead on Magic Origins, which wasn't exactly restrained, at least by Core Set standards.
You are dead wrong on this. It's one of the strongest constructed sets ever printed.
The closest points of comparison that come immediately to mind are Future Sight and New Phyrexia (block-ending small sets that rampaged all over constructed formats of every stripe) but neither of those had as significant an effect on Standard. OGW was full of ridiculous cards.
