I was seeing the same thing on shadowlands..... The latency wasn't showing but clicking on an ability or buff or opening a bank had anywhere from a 1 to 4 minute lag effect

This is definitely an exploit and EA and BIOWARE are allowing it to be used. When people can do something that makes the game misrepresent the numbers, it is an exploit and therefore should be handled like all other exploits. Instead EA and BIOWARE are claiming it isn't a bug and not wanting to do anything about. Typical lack of care for the users in the game and allowing the gold farmers to continue to grow in the game.

A suggestion - since ships we use are able to land planet side, why could you not summon your crew and ship to your location with a two hour cool down. Maybe a cartel coin purchase
