I don't see an assembly line in BuildCraft, neither conveyor belts.
Industrial Craft is about machines that (most of the time) kind of exist in real life, so why not add assembly lines, conveyor belts and sorting machines?
Aren't Miners featured in BuildCraft as well? Aren't Miners with a OD card like little quarries? Aren't Miners with a OV card like bigger quarries?
Surely, you make no sense here. Yes they're compatible, but so is the Timber Mod => Chainsaw, Drill Mod => Drill, JetPack0.3 => JetPack and many, many others.
It's kind of sad to have a good suggestion and instantly a forum troll *sigh*
If that wasn't trolling then I feel pitty. *checks if there's an ignore function as well*
Frankly, Viktor has a valid point. Everything you've said are direct replicas of what buildcraft offers, only with a different visual element. I understand that a lot of features from other mods are duplicated, but these are mods that are not designed specifically with buildcraft/IC in mind.
With the forge platform being opensource, these mods can be fully integrated without the need to replicate features.
On the topic of miners/quarries, these features where both implemented in each mod long before the forge platform became available and integration with other mods was of utterly no concern. Now they are being designed with everyone in mind, we don't have to repeat work.
Btw, Viktor has been around here for a while and has submitted many bug reports and suggestions. Not to mention the fact his comment was a statement of fact and not trolling. Your poor attempt at <sarcasm> 'pity' </sarcasm> is not well recieved by me at all.
