I'm totally fine with Trys switching names to play Grepolis in peace, and think it is a great idea.
It still looks like his Trys Asgon account is active on alpha, so he should probably shut that down before creating a new one. Don't want him to get banned while he is trying to make a fresh start of it.
And everybody else, when somebody leaves Grepolis, you treat them with respect. You might have been enemies, but that does not matter. Tip your hat, say good battle, and be done with it. That is one of the things Grepolis has taught me: Respect is important in real life too.
