Can Destiny be enjoyed alone?

[Locknuts]

I can get Destiny: The Taken King fairly cheap right now $AU55, but not so cheap that it's just a mindless buy.

I don't have any friends that own and Xbox One and I'm fairly anti social online. I love playing online shooters with randoms, but I don't make friends online and never play at consistent times so I won't be able to meet up with the same groups very often.

Can Destiny be enjoyed alone or at least can I just meet up with random people and have a good time?

Also, having kids I tend to quit games when I'm needed so will this effect the experience for others?
