My opinion:
Numbers according to Xtopher's main reply
1. It has been said that it depends on how the GM enables the PvP in the event, if it's via the NPC or the @pvpon command... My solution is to make it mandatory for the GMs to use the NPC to turn PvP on, and about the WoE PvP way or Normal PvP way, I pick the normal... WoE way means no Backslide, Knockbacks, etc.
2. Shield gave a good way to solve it, but I consider it could be a lot of time consuming, I mean we @whomap get the list of players and every time a person wants to get a recall we have to check the list of players and check if the player was indeed inside the event when we closed it.
3. Candies should not be allowed at all in GvG.
4. First of all, we will get a new event to take Annihilation place which means that the Annihilation tokens will turn into "[New event's name goes here] Tokens"... Hence my point of view that we should just be patient and wait for the new event to be announced.
Those are my opinions, you can differ what I agree with and what I don't.
