I haven’t ridden my MTB (apart from commuting) since I bought a GT Grade Alloy 105 at the end of June last year. In fact, I’ve just ditched the Mountain Kings & put some 700c Landcruisers on the 29er to replace my ancient Genesis Io for the daily trip to work & back. (So no I wouldn’t sell it, but it has changed duties.)
TBH, I bought the Grade so I could get more quality riding done from home, without having to rely on a lift from the other half to Cannock of such like. (I don’t drive.)
I didn’t realise I’d enjoy it so much. I gave up road riding about 20 years ago, but it’s been great to get back into it.
The GT is pretty capable off-road too, so all bases covered really.(I was never into jumps & big drops, so no great loss.)
