Any decrease in attack ETAs increases the possibility that a player can lose his whole fleet whilst sleeping or being AFK for any other reason (such as work). This is most likely to happen to the less active players but even we "addicts" could be caught in exceptional circumstances. Yes, there are steps one can take to keep ships safe but it's not always possible to wait for all fleets to get home before leaving the keyboard.

The idea of ETA 5/6 FCs is particularly worrying and might have the unfortunate effect of stopping almost all attacks on the top alliances. ATM it is possible to check for FCs just before landing - if you decide to land (or fail to check) then it's your own "fault".

The "stealth" attack proposal doesn't have those major drawbacks but it would share the characteristic of being more effective against the less active players - not necessarily a good move when we're trying desperately to attract (new) players rather than driving them away. (Although I agree with JBG that we're continuing to fail miserably in this area - for all kinds of reasons).
