The WinMTR is showing that the connection is dropping packets starting on the 3rd hop, at 192.sub-69-83-70.myvzw.com
This would mean that the problem isn’t with your PC or your hotspot/jetpack, but with the Verizon network or towers that your connection is routing through to get to the WoW servers.
If the problem only started recently there may be a new issue that Verizon needs to investigate at that point in the connection, or it may be something their engineers are already aware of. Either way, it should be something that Verizon would need to clear up for you to fix the packet loss which will provide more stability on the connection.
