Forgive me, I wasn't clear. There is no self-aggrandizement in complaining about somebody denying one's GB production. Much self-aggrandizement is on display in your post.
Actually, I wrote, "... those self-aggrandizing players..." not referring to DeletedUser26154 specifically, meaning mostly to in-the-game. However DeletedUser26154 did display that quality in subsequent posts.
I have only "flipped" or "leveled" someone else's Great Building intentionally out of ignorance when learning the game.
I now only "flip" or "level" as retalitation against those who Plunder my City. I Motivate or Polish
every single Freind and Neighbor
at least 6 times a week. Despite that, some advanced players still Plunder my City. When they do, I wait for their Great Buildings to become vulnerable to my "leveling" or "flipping" them. Often the opportunity escapes me.
Making Contributions to another Player's Great Building--of any amount at any Rewards Rank, at any time is part of the game, just as Plundering/getting Plundered.
