Grouping with the enemy?
I’m not sure how much of a benefit this would provide…and they’d have to accept they invite, wouldn’t they?
I could see this being helpful for finding my friends and setting up sparring matches. I enjoy competing against people I know for the fun of it.
But other than that, all I can see this being is annoying.
The problem is that is makes spying or just trolling for kicks that much easier to pull off. The enemy realm will invite their ‘friend’ to a group and he will report your team’s postion and movements while he follows the friendly zerg around. In the ideal situation, guilds will use guild chat and/or secure voice IPs to communicate. But this ain’t the ideal situation. You shouldn’t be able to communicate with enemy realms, let alone group with them, in WvWvW.
Nice to team up with one enemy if your common enemy is zerging you down.
