Hmmm... I became more of a fan of the villians during the later years of the line, so I'd have to go with either Lariska, Toa Mangai Tuyet, or Shadow Toa Akhmou because Akhmou would have essentially been unique, Tuyet and the Nui Stone would have been a cool collector's item, and the Federation of Fear was an awesome team and it always felt incomplete without a Lariska set.

It needs to have the same calibur of storytelling the previous series had, no matter what happens. Personally, I'd like to see a villain that could give Makuta Teridax a run for his money and have a hand in everything that goes down, but that's not to say there shouldn't be others with great characterisation either. For example, let's take "The Lord of Skull-Spiders" (hopefully this set has a different, non-google translated name): I would rather see this guy ensnare a Toa in its web and try to bite off their head before getting tag-teamed by the rest and defeated, over something lame, such as being on the verge of victory before tripping over its own webbing and falling into a volcano. And hopefully we're given a good reason why all the sets are giving us the tiny spiders and not other, smaller villians.

I'm not sure what Lego will do with HF, but I don't want them to cancel it for two reasons: the HF specific parts (which do have other uses- for example, I've seen some very cool looking Toa/Glatorian mocs using the helmets and I'm currently using two of the cores to hold together a modified Vortixx jaw and passing them off as earrings) and the fact that there are some HF fans out there, and I don't want Bionicle to be the theme that killed their line off. Some people still claim that HF killed off Bionicle, and that caused it (for them) to have a negative first impression from the start, even before the story was an issue. If that same bad taste is left in the mouths of the HF fans, the two sides might just end up switching places, and that could potentially shorten the lifespan of Bionicle's return.

I would like to see them come back, even if the story wasn't changed, because i'd just like to see a greater diversity amongst original lego constraction sets.

I haven't had a subscription since the Toa Mahri line ended, and while the magazine itself wasn't able to hold my interest for very long, I did regret not receiving the Bionicle comic and as such had no idea what was going on with the story (and thus stopped buying sets until HF came out after I graduated high school) because I lived in a house without power, internet, or cable at the time. I do however see how an age restriction might upset other people, and this decision could set them back a bit in that regard in addition to further annoying and alienating that particular group of fans. I enjoyed reading the Bionicle comics as they provided a more personal connection for me than going online and receiving the basic plot points of the story, and would strongly consider subscribing again if Lego included them for 2015, so not being able to have that access would personally annoy me too.
