I think that counts as being rude and lazy. Also wasteful. Drama would never approve.
At this rate I'll never be good enough for Drama... Teach me, Ken-senpai.
Maybe they should stop designing them that way then.
I was going to add this exact sentence into my post, but I figured it was already long and boring enough without going into detail, especially since I don't have any decent solutions to the problem.
The way I look at it, from a design perspective, is that you need to incentive people to run content. Tomes are a good incentive - people run dungeons now even though they're a slog. However, that doesn't make it any more or less enjoyable for players.
Maybe the answer is actually to shorten dungeons, rather than lengthen them. If you shorten the dungeons that you head into, people will be spending less time in them, which would feel like less of a grind. Trash is gonna be trash, but with less pulls you can design more interesting pulls almost like ST has (except ST's pulls are stupid because 24 people) or more akin to Trash pulls from T10/T11. Nothing difficult, mind you, but something to spice up the situation.
Putting in a new set of gear drops in every single patch is a crazy misuse of resources, in my opinion. Designing throwaway gear is almost as disappointing as the fact that we haven't seen a set of dungeon gear since 2.3. Odds are the gear set dropping tomorrow are gonna be trash like i100 or something totally pointless and fully for glamour purposes.
Like I started this post about nothing with, there is no easy fix to dungeons because it's hard to pin down what dungeons should even be used for in the endgame aside from getting an obligatory amount of tomes every week to buy gear that actually matters. The only way to make them relevant, I think, is to basically get rid of tome gear and turn them into drops from the dungeons instead. I can imagine how well that idea would go over, though.
