I saw this when you first posted and figured you would get ripped to shreds. I lurked but only joined the boards earlier this year (finally wanted to ask my own questions about Aulani!), but yeesh, park loyalty is strong.
My perspective is that no one should bother trying to compare DLR to WDW. They are different parks/resorts, making for different vacations, and everyone needs to approach them differently. My family likes both for what they are, and none of us can say which "park" we prefer b/c there are pros/cons to MK vs DL, but we have opinions on which "vacation" we prefer.
I grew up going to WDW, but we recently moved out west, so at some point my DLR visits will become more numerous than WDW. I think everyone who lives physically closer to DLR and cares about Disney parks is somewhat vested in the state of DLR, and to that point, we should be, b/c OP makes some valid observations about overcrowding, specifically for DL park. Our recent April trip was insanity. Our only previous trip was in the summer, the year Carsland opened, when we happened to be in CA for a wedding and couldn't pass up the opportunity to go to
Disneyland. The summer crowds (June) made zero impression on me. Fast forward a few years to April, not even during spring break, and holy cow - insanity. Yes, there was clumping getting into Tomorrowland that cleared up, but the Adventureland clumping never cleared up... and getting around the carousel was just awful. My family of 4 did the single-file hand-holding thing to get anywhere and not lose each other. As the family fastpass runner, it was exhausting, and by day 3 DH and I were taking turns with that job. The kids begged to go to Pinocchio's Workshop, just worn out from the crowds; when asked what his favorite part of Disneyland was after we returned, DS7 said "California Adventure". My personal goal for this trip was to hit every ride that isn't in WDW, and we didn't even manage to do that. For anyone who thinks waits for some of the dark rides in Fantasyland are always short - nope, not then. We utilized the heck out of fastpasses, but that only goes so far when they're nearly gone by the early afternoon. Say what you will about FP+, but we could utilize the early morning in WDW, have 3 planned fastpasses for the afternoon, and be there an entire day without standing in any crazy lines rather than giving up by mid-afternoon. I know DLR regulars hate the idea of FP+, but it does increase the value of park tickets from that perspective for other yearly guests... just not how APs do things, I realize.
Things have changed in the last few years, and closing down attractions for new construction, while necessary, is only wisely done if park capacity is reduced. Maybe it gets better once construction is completed and flow is returned, but that will be a while! It's clear management put zero thought into this issue.
Regarding the rest of it, I have only had lovely interactions with all Disney CMs in all the parks and Aulani, although I'm sure one day that will change. We think Bug's Land is adorable, especially if you've seen the movie recently and pick up on all the details. The Pier, well, yeah, it's ok, with you on that. At least it's not crowded...
