You left out a lot of the most annoying ones. Such as only getting four mails before no more can come in. Not being able to send your alt a in game mail. Heck not even being able to give rights to your alt even if you have them in your FC and can click on their name.
Then there is not having a pet And a mount out. No minions in dungeons. Not being able to talk to friends in tells while in dungeons.
The list litterally goes on and on. But these are some i just can't wrap my head around.
