IMO, you need a better plan to keep TI alive, or at least make it seem like you care.
Also the least that could be done is for you to come up with some kind of reward for people that have played for years in TI & decide to move to Dion. For example, why am I not able to sell any items via the AH and transfer the balance to Dion? (Not that someone would buy anyway, since you're killing TI.)
With the move of opening a new server it feels like you're executing the final blow to the server.
Please think of something because as soon as the hype of Dion wears out & the usual mass-trolls that just jump between servers, leave, then the loyal people that trusted in the longevity of your projects will also not keep investing time here.
p.s: Also, please keep in mind the amount of players that do not actively spam forums or discord and just enjoy the game. The spammers, the trolls & the people asking for a new server did not contribute into making this project lasting 7 years long!
