The trails might not have, but riders and their kit have. More armour on display, more full facers, bigger bikes etc - sort of peer pressure really, I can see why people ask.
Look what bikes are used for 4X and ask yourself again if a Reign isnt bigger enough.....
But, probably more comfy on a big bike, depending on what you're riding down. Personally I go out there for long, techie footpath type descents, rather than the pistes, so a "trail" bike is perfect for me (and adequate for the odd day in the bike parks).
10 weeks in total over the last 2 years or so, no torn tyres (single ply HRs), 3 flats between 2 of us, no damaged mechs and a set of pads will do me for a least a few weeks in the dry.
Go and have fun.
