What happened here is making a lot of players very upset.
Why on earth would a company start an event for servers that are going to get merged without a single notice like "sorry, once the merge happens all scores of the event will get lost".
I scored 4.6M wall damage before the merge and spent a lot of energy potions (and lost units) to get this far. Not to mention that, as always, regular players have to compete with other players who just farm their dozens of alt accounts.
Before the event ends, there is no PVP on the merged realms. But if you think the announcement that attackers lists get reset and there will be no revenge hits after a merge, you are wrong. If you had an ingame message with a revenge link (e.g. to your alt accounts), you can still hit them back after the merge. Poorly executed on the development side.
Everyone who is on the merged realms does not know if he wants to laugh hard or cry, seeing other players getting new siege numbers, while they literally can not compete.
Not to mention that clearing neutral cities does not count as wall damage.
I am disappointed on this one! A lot!
