So I just soent about 20 minutes tinkering with Dartcraft with the things I already had in my relatively new FTB Unleashed SSP world and.. Wow..
With very few starting materials I now run at about 4x vanilla speed on the ground, and have made myself some tools that afaik resemble somewhat enchanted diamond tools.
The tools are pretty darn good, but look at what they do. The force axe is probably the easiest to make where the only thing you'll be putting on it at higher tiers is more sugar. Basically, it helps you get started by powering through the most tedious thing ever, chopping down trees. Treecapitator does this too, but dartcraft makes you work for it a little. Of course, once you have a tree farm set up, why use a force axe, right?
The armor is okay, but it doesn't do a lot of things that other armors will do and actually punching stuff will rapidly damage the armor.
The other tools are notable for their area modes and (once you get your upgrades high enough) fortune 4. Other than that, Tinker's construct tools tend to be better. A cobblestone hammer, for example, can be acquired very early (using cheap blocks of copper/tin for the tool forge) and made without a smeltery. It'll clear out vast areas, leaving in place more valuable ores alone that you'll want to use fortune on later. I'd go on more, but there are literally entire threads about tinker's construct tools already.
Really? I understand people have been saying this is OP for a while now, along with spoils bags and stuff. Another thing I noticed is the fact you can, in fact, wrench full diamond chests. Screw the force and ender bag, i'll take everything I need for a massive spelunking trip in one inventory space sized diamond chest, please!
Okay, you've totally missed the HUGE utility of force packs and force belts. The rod upgrades are rather good (holding=store mobs like a safari net, sight=multiple use nightvision potion, return=reset-able following link book as long as you're in the same dimension), and functionally expand your hotbar via using them from the belt via the number pad.
Force packs are AMAZING with item cards and crafting item cards. With an item card set to cobblestone in a force pack, all the cobblestone you pick up will get sucked into the force pack (which only has to be on your bar if you want to pull stuff out). With a crafting item card set to make compressed cobblestone out of cobblestone, all the cobblestone you pick up will get sucked up into the force pack and compressed! That's the point where I break out 2-3 cobblestone hammers and go nuts. You can do the same thing with ingots if one makes a fortune+smelting tinker tool or a heat/grinding force pick/power drill by having the crafting card make storage blocks out of them.
In short, derping around with force wrench'd chests as a means of extra inventory is just wasting time micromanaging something dartcraft does WAAAAY better for you (check out force pipes too). I like that I can force wrench a chest when I'm making the transition from chests to AE so that I can just pick up all the stuff and put it next to an import bus or whatever, but it's not as good a solution for spelunking.
And really, much of this is swiftly overshadowed by someone using a turtle with a quarrying program or a quarry or a laser drill.
