Auto attack: A complete battle system

[Betelgeuzah]

if you think I thought that FFXIV was the pinnacle of button mashing, you might want to work on your reading skills.

Then you shouldn't compare games that require more button mashing (and as the result do not require as much communication) with a game that requires more communication but doesn't require as much button mashing. But it's okay, as you are in China.

as WoW has shown that makes it hard to build a community.

And then you go and assume this is why the above (unproven) statement is true. Factors such as you can solo till max level, leveling alts is encouraged so the servers will be filled with people that have multiple characters with different names, and the auto-group feature that makes grouping across servers possible, making you group with players you will never meet again don't affect the outcome, right? If you can prove that what you propose is why "WoW doesn't have a good community", then please do so.

WHY IS NO AA a good thing?

"Why AA is a bad thing" = "Why no AA is a good thing". What's the point as the former has been discussed times and times again?

Combat becomes more automated, this is not acceptable.
The game is dumbed down for PC players for the sake of console players.
The game is dumbed down because the servers can't handle anything more complex than half-automated combat system.
The game is dumbed down so that players can chat using text-based functions instead of using a voice chat like every other MMORPG in existence.
The change requires resources and time and the end result is what was listed above.
