Hey there,
Ok, so this is an interesting situation, thank you for bringing it up. First, a little history and then what we are talking about on the team to resolve it.
For a long time we never had the PvP Mission terminals inside of Warzones or Arenas. And so there was a pretty logical reason to allow Mission sharing within Warzones and Arenas. However, since that change happened that need has certainly gone down or vanished entirely.
We hadn't heard about players abusing Mission sharing as a form of harassment, so thanks for the report there. In addition to that we are talking about a couple of different changes we can make:
- Stopping Mission sharing in Warzones and Arenas - As mentioned above, since the addition of the terminals we are not sure we need to allow sharing anymore. Especially if it is being abused.
- Tie /ignore to blocking Mission sharing as well.
Let us know your thoughts on both of these options. It is worth noting that we are at build lock for 7.3.1 (you should expect this real soon) so these changes wouldn't be possible until 7.4.
Thanks again for the question and feedback.
