As it is a lot of fun to play on EU 5 with a level restriction up to 20, I wish I would never level up and could stay there. Respec is sadly not a good idea so I thought about a tiny retirement on level 20.
Of course you shouldnt get a loompoint. I thought of around 10k gold which sounds reasonable. If someone else has an idea, hands up!
Another idea:
create a new class: EU 5 Character. He can play on any server but level limit is 20. He starts at level 1 as any other character and cannot be a main, such as an alt character.
They can retire at level 20 and get some bonus (not a loompoint), maybe some gold and get some more xp per gen, maybe +30 like (if that is the case then you cannot undo the character, that means you cannot remove the level 20 cap) any other.
These characters would be specially used for the EU5 server. The gold earned by the retirement cannot be traded to other characters.
This does of course needs some thoughts as there could be some problems. Example: level 20 is quick to reach, 10k each time you can easily make enough money to ride a plated charger. on EU5 that is of course not possible but on other servers it could be. not sure if that will be possible then.
