In my opinion, to enter the wild, your deck has to contain at least 1 wild card. I got bored with pure standard deck in ranked mode, i face sometimes 3 in a row. If you have standard deck you should know that your deck is stronger in standard. I mostly win with them but i want to take a break of that standard fiesta and i dont want to face it all over again. Sure some deck use only 2 wild cards(crack for shaman etc.) but when i go to fatique and still no wild card im just sad.I hope they will intorduce that.
wild's wild, people can play what they want. that's the beauty of it. People playing standard decks in wild makes no difference. Only thing that really needs to happen to fix wild is a couple card nerfs and them putting the packs/adventures back in the shop.
It will happen less after the next standard rotation, right now the difference between standard and wild is only naxx and gvg, so it's possible to put together a decent deck (in wild powerlevel terms) without using wild cards, but in few months wild-only content will more then double itself with BRM+TGT+LOE cards becoming wild-only, it will be much harder to play against well built wild decks without cards from the 5 wild-only sets.
