Didn’t get any. Don’t get me wrong, I’m not one of those “HF set are the worst things ever!” people; I just lost interest after Bionicle ended, and after I regained some interest, the more recent ones were too expensive.
2010:
Furno, Surge, Stringer, and Meltdown
2011:
Evo, Nex, Jetbug, Witch Doctor
2012:
Furno
2013:
Pyrox
2014:
Crystal Beast
Basically, I would’ve bought more sets in 2012 if Lego LOTR hadn’t come out After that, it just became a tradition of mine to buy an HF set because I still liked constraction.
I wouldn’t say that I have a collection; I’ve just kept (most of) my favorite sets built/modified.
