My general policy is that if someone else wants to do something that the pack was CLEARLY not designed to do (like use creative, turn off hardcore, /give items, change core mechanics to give themselves an advantage, etc), they are only really hurting themselves. The pack was not designed for that, and unless the player thinks they know better than the pack creator (in which case, the player should start making packs themselves and prove it), you are ruining the experience as intended. This is what I consider to be "cheating."
Now, that being said, if "cheating" makes the game more enjoyable to you, go for it. Again, it doesn't really affect me. But don't pretend that you're playing the same game as everyone else (cause you're not), that you are playing the game the way it's supposed to be played (cause you're not), or that your game is representative of anything but your own personal experience (cause it isn't). I would also hope that anyone "cheating" would refrain from providing advice to new people/people who aren't cheating, as their experiences with a modified game will certainly affect their playstyle and the choices they make, which can be confusing to a new player.
As for "cowardly" gameplay, I like that wording. It's perfect, and describes me perfectly, and I have no shame about it. GIANT wall, GIANT trench, gun out all the time, never ever go anywhere ever with mobs, run like a little wussy in the city, because, well, I am. Mobs are scarey.
All good points, but that wasn't my point whatsoever.
My problem is simple. Do something outside the bounds of the default pack (and there's no real rule to this, it's got to be common sense that you're doing something along those lines [which is where the problem originates fwiw]). Then, come on here and talk from an air of superiority or wisdom that you know how x fits into y, etc... and essentially marginalize the work and effort people have put in before you on going over these situations. Rehash them, argue with them, and then slip up and disclose original change (since there's nobody but you that will ever know you're doing anything different than what everyone else is). And until that last bit happens, everyone else has to rehash things for themselves, ensure that there isn't a bug, etc... Essentially, waste their valuable time, and doubt themselves for no reason because what? because someone wasn't playing the same game as everyone else.
This isn't the first instance, nor will this be the last. It happens in support of all kinds all the time. People hide what they screwed up till the situation forces them to divulge said issue, then it's back pedal time. If people were up front, courteous, to the point (I fail at that miserably), and worked towards a common goal, well, then this wouldn't be the internet would it?
Cheating, modifying configs to give you an advantage (regardless if there is RP attached), etc.. Nobody cares, nor will anyone know unless you tell them. Anything you do in the confines of your home, as long as it stays there, regardless of what it is, should be your business, and nobody else's. Bring it out into the open tho? Fair game.
On the other hand, crappy system, disable mod cause it's causing too much lag? grey area. why? Cause, for example ZA is a core mod mechanic. Disable bibliocraft? Not so much. grey area. dunno. Not worried so much about that. Not worried about any of it really, again, see last paragraph.
But, since day one, Iskandar, Eyamaz, when they made their packs, they specifically outline no changing of mods, etc.. cause you will break the pack, so thus, no support. It's easy when they flat out say "I added optifine and now pack won't run, wtf?"
