I've disenchanted every wild card and have and never regretted it. As a F2P player, the large influx of dust allows me a lot more freedom to stay competitive in standard.
Not only that, I'm of the opinion that if you choose to play wild, you choose to expose yourself to the clusterf**k of overpowered bs that would undoubtedly be a source of endless frustration and would have 0 right to complain about balance because that's literally what you signed up for when you chose to play it. (0 sympathy for people that whine wild is unbalanced).
Just my 2 cents
