GCW Invasion

GCW Invasion
This idea/suggestion is Open. You can respond to ask questions or discuss the idea and either vote it up or down if you believe it should or should not be implemented, respectively. Popular suggestions and ideas will be considered by the development team to become reality in-game.
Proposal
Make it so if you attack built structures such as the turrets and barricades you are flagged SF for PvP.
Justification
Having people come into an invasion and destroy all the structures to prevent being able to pick up the quests with no way to defend or fight back does not make sense. There needs to be consequences to actions instead of a free troll opportunity.
Motivation
Multiple times there has been characters show up to an invasion flag combatant destroy all the barricades and turrets and leave just to troll or deny content. The problem is there is no way to defend or prevent the uncontested destruction of the structures.
I am suggesting a change to City Invasion mechanics to allow for the defense of built structures during the invasion from combatants being allowed to destroy everything and leave just to troll groups or to freely collect a collection for a badge. There should be a mechanic that allows for the forced flagging of characters that attack structures just like the one used to flag if the General is attacked.
