I don't play anymore (I gave up when they introduced Runestones), but I agree with the general consensus of the group here, that Wild shouldn't have any bans; if anything, it defeats the purpose of the game mode.
Being a player that mostly played wild in my last year of playing, I would say that I do think that It deserves a little more attention in terms of balancing however since they very rarely touch any of the cards despite different combinations becoming more and more powerful as additional synergies emerge from new card sets that are added. An example would be Illuminate and Shadow Essence, which is a combination that can allow broken turns on as early as turn 2 with the coin. I am not saying that particular combination needs to be fixed, it's more an example of how two cards that are fine in a vacuum can become a problem together.
The recent nerfs in standard shook up the meta quite a lot, it would be nice for wild to have a shake-up like that every now and again, by reducing the power levels of some of the dominant decks that polarize wild, but without actually destroying those decks in the process.
