I like the concept an design and i can deal with the laggs, but it is quite anoiing, that the game keeps hanging up. I guess 3/4 of my lost Arena-Battles due to Server-Issues...
Found some suggestions among the comments and will try them, but i will stop to play this game if it doesn't help, sorry

yesterday's patch seems to have solved the last of the arena/caverns freeze problems. hope you're still playing!
