I would say by the lack of complaints from others, and not really seeing any other threads about it that it likely isn't a wide spread issue.
Personally the only connection issues I have had happen before the battle or at the end. Never right in the middle of it. Like it either fails to connect correctly when loading into a player base, and occasionally if my internet is tripping up it will sort of freeze on the victory screen and not progress past that requiring me to reload the game.
I would suggest sending in a ticket if you haven't already to try and troubleshoot any connection issues.
I guess I'm the ONLY one on the planet that has experienced this issue!
Now I know what if *#&!feels like when the whole world ignores me!!!!!!
