My lord, I just spend an hour reading this whole topic from the first page and it went down from disliking Yogscast to disliking their fanbase and fear of spamming, to Techinic/Tekkit permissions arguments and more, even one going as far to not play FTB if the Yogscast played it. Seriously? Talk about derailing and overreacting.
If you dislike the Yogscast, fine, to each their own cookie. After all, we're free to have our own opinions, but to dislike the fact/possibility of the Yogscast playing FTB in fear of what it's fanbase may possibly bring to the forums on grounds of immaturity and spamming....well I'm sorry, but that just makes you sound like a petty elitist. Every community has their rotten apples, even the FTB forums have their share of them and no one can really deny that. So whether their community joins up on these forums or not should not even be a reason to dislike it, you're not forced to read or reply to their topics so why bother hating on it?
In my opinion, I'm fine with the Yogscast moving over to FTB, I've stopped watching their Tekkit series ever since I started playing FTB, it's just confusing to do so and I welcome a new series with the FTB pack by them.
I also look forward to a potential modpack by them, in all honesty the Yogbox was pretty funny and I liked the whole survival/RPG aspect of it, which is something that FTB doesn't really provide yet.
As for their community, to say that a majority is immature....yeah, I can agree, to claim an age range....that's just generalization, I'm 27 myself and I like their humor (or humour as the Brits say it). To fear that they will clog up the forums with noob acts and spamming...that's just something that will inevitably happen anyway, it's part of every internet community. I mean, about every forum dedicated to minecraft has it (it's even worse for MMO games!)
All in all, people should stop worrying about what if's and more concern themselves to what they like rather then bother with what they dislike.
