High Home Latency Low World Latency

[Anastezia-outland]

Hello.
I thought to get back to game and start subscription.
I logged into my 20 lvl character and wanted to check what is going with game.
Then I joined Dungeon Finder, found team and started to do it.
But after 20-30 min I got disconnect.
I closed the game client, run it again, logged into game, picked one of my char and tried to enter world, but again got disconnect.
After 10 - 20 min I tried the same steps, and got inside world.
And latency monitor showed around 10 000 - 20 000 ms home latency / 70 ms world latency . During around 30 min playing home latency got to it common value 70. I repeated all these steps many times to check.
So, steps are -
1 - Log into game.
2 - Pick character and enter world, latency home 70 / world 70.
3 - Start dungeon.
4 - After 20-30 min playing dungeon get disconnect.
5 - Log into game.
5 - Pick character and trying to enter world.
7 - Get disconnect.
8 - Wait 10-20 min
9 - Log into game again.
10 - Pick character and trying to enter world
11 - Enter world, latency home 10 000 - 20 000 / world 70
12 - Wait inside the game around 30 min, home latency gradually get to 70 and i have home 70 / world 70
13 - Then again join dungeon.
14 - Play 10-20 min inside dungeon and get disconnect.
I thought to fix it.
I removed all blizzard folders in AppData, ProgramData.
I removed WTF, Cash, Interface Folders, got completely fresh game, flush dns etc. and repeated all the steps. result was the same: disconnect from the game with insane high home latency.
In other hand i did the same with character on other low populated realm
and didn’t got disconnect at all.
Other online games like eveonline, world of tank run smoothly. No one get disconnect.
I ask Blizzard to allow me transfer all my mains away from lagging Outland to any low populated realm. Then I will pay subscription for playing.
THX!
