If you could change anything about the series, what would it be?

Well, there'd be a shitton more Rarity episodes, for starters

 

Hmmm...I'd write out the "Sonic Rainboom" episode, too. Out of sight, out of mind...

 

Ooo, another big one is take Twilight's wings away and make her have no special focus in comparison to the other mane 6 members. Just one of the gang, rather than the leader of a crew. I think the should would've benefited greatly if that were the case from the get go. 

 

That's all I can think of at the moment
 

Raridash episode:There have been multiple episode who put two ponies at the same time(Rarity-Applejack,Twilight-Rainbow Dash,Fluttershy-Rainbow Dash...),but we still have to see an episode starred by Rarity and Rainbow Dash.
Of course there're other pairings that can be exploited,like Twijack,Appleshy(I don't exactly count Bats! as a Appleshy episode),etc,who need building,but,if I had to choose,Raridash has the most chemish of them all.

Oh yeahh, and this.

 

All of my this. Even Rarity's TVTropes page makes note of how absent their friendship is Throw Rarity's girlish charisma and RD's boyish charisma, and all of the beautiful constrasts and similarities between the two characters and I dare say these two have the potential for a better than Rarijack dynamic, but meh. I blame Corey Powell
