Still.. Fast and double.. macerator, pulverizer.. etc..
Slow and triple.. Cristalization...
Multiblock.. Thaumcraft..
I understand that originality can be found in variety, but again, we have a ton, A TON, of ways to work on ores and stuff.. Doing that again is just.. Useless. It kinda sucks, but it is.. Instead of oil, vines. But its still the same idea:
Input 1 ore,output 2 or 3 ores, machine as the way, and vines (instead of oil) as the price. It is still the same thing that 5 mods already do.
For the other part, grappling hook.. I kinda want to see that, i use the better dungeons one.. but it doesnt work too well, mobility based armour, machinemuse modular power suits has everything you could ever need except the omnipotence of gravi. And.. tinkers construct vine tools.. Again, i dont wanna be an asshole, but as you pain the mod it seems like another machine chain to multiply your ores with a set of armour and some tools.. that are even gonna be from another mod! So.. It's not original at all.. The only idea that came from your head until now, is to use vines as the focus. Thats it.. Everything else has been seen somewhere else (and in large quantities).. you can enter the minecraft forums and you are not going to be able to scroll 2 pages without seeing a new revolucionary "Multiply your ores, craft your new armour that does wonderfull stuff and get some new tools!!" mod.. And this one is, just that. But with vines. Thats the truth :S As you said, the main heart of the mod is: Using vine (fine) and machines (fine).. But what you do with that 2 things, is just the same shit we see every day we open minecraft in a ftb pack.
There is a lot you could do with "vine" maybe instead of trying to create a whole new revolucionary and original way of doing the same thing we always do, you could try to orient it in some way it goes with the mods we already had, instead of overlapping them... Find a way to turn find into fuel, do some nature stuff and make some crops, we havent seen already a mod that gives REAL, GOOD, farming. Yeah, we have like.. what? 4 or 5 new types of crop.. (and 2 of them are barley and do the same thing.. ) and some new trees.. Use your vine for stuff we dont have, not for stuff we already have in every single mod. And if you are going to re use the same idea that everyone is reusing, then dont call it original, 'cause it isnt :S
