I thought that BuildCraft pipe explosions were quite intentional - whether
every explosion was intended I cannot say (but I know they've never exploded on
me without good reason - the last instance I can remember where some guy had them do it under "mysterious circumstances" turned out to be a
misplaced a chunk loader), but I'd hardly call the full removal of pipe explosions a "fix". A counter for
Thermal Expansion, maybe, which'd recently undermined much of BuildCraft's power transportation system (prompting a manta around these parts of "just use conduits!" being chanted at everyone who asked how to use it), but a
bug fix? Seriously? And I suppose it was just a coincidence that the same update removed transfer loss?
Now TE is stand-alone, I'm seeing posts calling for the death of BC - and I'll just
bet they're because TE is easier on the server processor. Yeah. That's what it is. Not because it's simpler and easier to set up a base with it. But let's face it, BuildCraft makes for a much more interesting potato knish factory.
(I also wasn't aware that BuildCraft pipes could now take fluids and items at the same time, though when it comes to that, I wasn't aware that ANY pipe system could.)
MystCraft is another great example of player mentality at the moment - it really is a game-breaker in that I can't count the number of systems it circumvents (prompting players to simply
skip them), but any suggestion of removing it from the main packs and there's an uproar (because that's where the bar's been raised!). I'd argue that what "makes a better game" and what "players want" aren't always the same thing, and all this leads to players getting bored of their worlds sooner.
Whether players who want "simple ways to the top" are "right" or not is clearly a silly argument, as it boils down to opinion and everyone's got their own about what's fun for them. But I do get the impression that most players are no longer taking the long routes, leading to a mod maker mentality of "simplify or die", and I can certainly see how a pack without certain mods (new or old) will lead to much more interesting problems to solve for some players.
Speaking of, granted MystCraft has been around for ages, but to the best of my understanding liquid UU is relatively new. If grinding out simple books to access an ocean of the stuff isn't a clear example of power creep, I'm not sure what is.
And don't get me started on Morph. I don't like the idea of adding it to the main packs at all.
