please do so, I know we are charged of safety of our account, but If nostalrius is breached we are pretty much fucked by the policy you ordain. I would feel way safer if I can lock/change pw/Change mail from and forum then to log in? what and change PW ingame? meaning if someone gets hold of my PW anyhow you are pretty much skewered and can't do shit about it.
blizzard had leak of passwords, I had to change it because they leaked, not me. And that it never happened doesn't matter it can happen, I never had stolen account aswell, but I like to have some insurance.
Please rethink this, as EVEN in RL if you lose your credit card you can still block your account from being completely ravaged, something like this must be here in place to ensure the safety of accounts even from your side, looking away from problem is not a solution.
