One day SBI you might realise that the casual players your so concerned about not upsetting wont be around in the long turn
The "hardcore" keep merging into larger and more powerful blocs until eventually they bore themselves out of their own game. The politics become stagnant and the game becomes monotonous or they actually ally their way out of having any competent enemies at all because all the competent players have finally been forced to join the same team (or they lose badly enough to give up and quit).
I'm not sure megas -- or their leaders, anyway -- realize that they would surely have more fun if battles and politics were more fluid. Smaller alliances with shifting loyalties. Fewer allies and more enemies. The drive to "win" can end up destroying all the things that made the game fun.
