I suppose most hobbies are like that... I don't have much of a hobby outside of pokemon so I can't comment on them but i'm sure people have varied tastes within one hobby.
I think it's interesting too and it makes for some interesting discussion and heated debates concerning things like RNG, Chaining and what makes a challenging way to hunt.
I'm sure i'll warm to REing, it's technically just like SRing but you're not resetting the game (or frame). I just can't seem to get into it as much as Eggs or SR.
It is more exciting with B+W's double grass I think, everytime a Petilil appears I think it's shiny

They're so similar to normal in colour. Also if I get two of the same pokemon I think one looks slightly different to the other for a split second, dunno why but they just do to me.
