Element bearers who are powerless without the elements, and yet alwais are send to dangers without any backup anyway, who cares that one of tham die in action, oh wait, than nothink will stop Discord and other super villans, uh.
Celestia who alwais sit behind frontline until it is to late. Luna who alwais oversleep entire action, she want help but she never get the chance. Shinning Armor who broke Twilight heart on the wedding and whos shield is so powerful that that who needs army of Unicorns or Celestia and Luna, if Shinning Armor can single horn stop entire army. And Cadence who is less of a fighter and more of a power buff for Shinning Armor.
Do not get me wrong, I realy like Luna, have nothink again Celestia and like Mane 6 ( especialy Twilight ), I find Shinning Armor and Cadence fine for me.
It is just that I do not like many of they actions to much, element bearers are the only ones who can use artifacts to defeat the most powerful evil, but they are just mortal ponies unlike Celestia and Luna, and unlike military what is expendable, if one element die, it is game over, and yet they are all time taking heavy risk with no backup.
Celestia is ment to be so powerful and protect her kindgom, and yet she was never send to assist in anythink, even fight again chrysalis took just 15 secounds, it would be so epic if Celestia would fight alongside mane 6. The fact that Luna is so ignored is annoying me and every Luna fan, we just would love to see her assisting mane 6, and using her dark powers again evil. Shinning Armor is OP, how can 1 Unicorn be able to stop entire army from invading, if he would be buffed by Celestia magic than ok, but to keep shield on his own, OP. Cadence did fine job to be Shinning Armor buff ( alicorn with no fighting expereince still makes extremaly good magic source for those who protect Equestria, still I wonder do she will even realize that her and Shinning Armor shield what reflect changelings could actualy kill or badly hurt many of tham, and that after the wedding, changelings are probably dying from hunger, Cadence what I would realy like would order to search for injured and defeated changelings and supply tham with her magic ( she is Alicorn of Love, so she seems best to feed poor changelings and negotiate peace ).
So yea, Like tham, do not like what they are doing, hoping that they will do the right think in season 3.
