This change is a game experience issue to change the pacing of and access to assault vs. defend a base. Doesn't seem like worth cancelling a subscription on, but it's your money. I could see if there are features you are SUPPOSED to have, but don't due to bugs, etc... Means you're a paying customer that are not getting the content you paid for. This though? Nah.
The changes of the router ranges need to be increased, I would suggest tripled or quadrupled. The blue area that lights up for everyone needs to be lit up only for the person who drops the routers spire so that a person who is dual boxing cannot see the area where the spire is located.
