As far as my understanding goes, let me try to get some certain aspects of this correct.
- Ultimate is a 100% locked pack, is this correct? Does this mean that if redpower makes an update to 1.5.2, the rest of the pack would move upwards accordingly? Or if she just makes updates in general?
As far as the 3 new modpacks go... From what I can tell, direwolf20's is just his own modpack project and it's attempting to focus around what he's always been doing, but with more updates and a few new mods added to his pack.
However, Unleashed and Unhinged seem to be the love children of FTB Ultimate... Divided, but with some minor added content to their packs...
Unleashed is geared more towards having a lot of mods and a lot of things to do, but you're able to get there easily.
Unhinged seems to be more devoted to having a minuscule amount of content, but making the game more extreme for the player to progress as fast. Hence being more devoted to GregoriousT's guidance in the modpack's creation.
Personally, I don't like any of the new modpacks. I feel as though Ultimate brought that very necessary balance between having a lot of content and having to deal with the harshness of Gregtech (as Gregtech made the easymode practically vanish). However, it almost feels like you're pushing these modpacks onto us when you tell people that Ultimate and other packs won't be updated anymore. I know that it's something that's probably unavoidable, however the divide between Unhinged and Unleashed makes me extremely uncomfortable as a server owner.
TLDR: I would have no problem with Unleashed if you would just add gregtech to it by default and let the people who are going to have to deal with running these packs on their clients in the first place choose whether or not to disable said mod. From what I've seen, most Unleashed servers are just adding it to their packs anyway.
