I have a few wallets at blockchain.info.
And there are a two things that bother me:

What happenes if I lose my email account for any reason (got hacked, provider goes bankrupt, password lost)?
Because to log in, blockchain.info sends me a confirmation mail to my address each time. If I do not get that, how do I log in?

And what happened to the mnemonic from the legacy wallet? In the new version I have not seen it.
Has it been replaced by the 12 recovery words?
