if by worth you men Damage dealing or support skills, nope but if you want to gain extra costumes and polymorphs and do extra storyline yes. you also gain skill points
the eso web page says
"To qualify for the free crowns, you must have logged in to the game between January 1, 2017 at 2:00AM EST, and February 7, 2019 at 2:00AM EST"
I read that to mean that you will have had to log in once between January 2017 and February 2019 thats a two year window.
I'm saying once because not even ZOS would expect you to log in every day for over 2 years.
I have, just wonder how long it will take them to sort it out though, looking at recent history of the way support works(especially for EU customers) i wont be holding my breath.
For those login since January -ish received 500 crowns. So what are your plans for it?
Save them to buy riding lessons so if I decide to create a new character, I don't have endure another ridiculous 6 months feeding my mount.
