At the end, this all amouts to one thing only. Not progress of one particular (or two) players having bought an age of tech with diamonds. Not the "stupid" 1 troop 7 rogues tactic. Not about unable to retaliate. All it is it always zoomes down to the plundering.
If you have a structured town, streamline and synchronise all buildings (coins, supplies, goods, GB's) to one particular time a day - collection is done in a flash of a few seconds. Who can plunder then ? The game gives everyone the possibility to avoid plundering, if players do not make use of it so who is to blame ? I don't think INNO.
No one can tell me that - for example - 20 seconds at breakfast in the morning are not possible.
If nothing to plunder, then complaining and moaning and whining about it isn't happen.
Many forget that this is a fighting game, PvP, GvG, and all is build around that.
Else might well go and play Farmville on a wellknown social media site.
