I agree entirely, and its a very good thing to put out there that I forgot, saving such a mod is great ^.^
honestly if they could merge the Immibus and ThunderDark version, it would be even better, because both have things the other doesnt, and then its well rounded, instead of Immibis being more for technic and thunderdark being better suited for tekkit.
ThunderDark is the one that has the most support, noticably, and the best of features for tekkit, and it seems most people request that one for tekkit anyways, but the issue was brought up on the server I promote as well "well that would make it a custom tekkit and then every player would have to add the mod to their clients, which is something that most dont know how to do, and makes it harder to play for newcomers".... So currently its a bit of a pickle, and we may just be disabled the immibus on the server, because it doesnt do any good, and has some pretty big bugs (forcefield glitching, not filling everything in [iE leaving massive holes in it everywhere], lag, etc.)
Which when I modded my Tekkit, I didnt have with the ThunderDark... its just better for Tekkit, which is focused on the multiplayer.
