Okay, first of all, when attacking a monster on an EA shard two things will happen: your character goes into war mode automatically, and war/peace mode toggling invokes the 1 second (.5 second delay on RunUO/ServUO shards by default) action delay, which is basically the action delay that happens when you try to move another object or something too soon.
To replicate what I'm saying, go on an EA shard and follow these steps:
Go and attack something and keep an eye on your war/peace, start out in peace mode and use attack last, spam attack last on it and note that you'll have a wall of action delay messages and you'll also note that you were forced into war mode automatically. You will absolutely never be successful going into war mode and equipping a weapon at the same time on an EA shard.
This was basically put on EA shards back in Mondain's Legacy so people couldn't just run around spamming attack last.. check it out. Totally different from free shards.
