I tend to agree, but for a different reason. At least for me, my master password was 10+ characters, with letters (cap and lowercase), numbers, and symbols, so even if that outgoing traffic on the LastPass servers was something that could be hacked, I feel pretty safe.
That said, I have gone and changed my passwords for Evernote and my main email accounts. For now, I’m storing them on paper and in Keeper on my Android phone, and then I’ll go enter them into LastPass after the server is accessible and I can change my master password. Probably unnecessary, but better safe than sorry.
