The problem with shutting down dev bases now is that level 11's can't attack level 4's, like they would have been able to do in the past. This makes cnfo a real problem, even on Tat. They also removed a shit ton of bases from they system. My donor base used to be ranked in the 5 millions; I keep it at 1 medal. When prestige came in, it jumped up to around #200,000. So, ~5 million bases were removed. It used to be that when the dev bases went down, you wouldn't get cnfo, instead you'd draw bizarre, dead bases. Over the course of a few days, the level would drop from your level way down. I suspect these zombie bases were among the 5 million that got erased.
They really need to keep the dev bases, but lower the gear rewards for conflicts. They should either keep the loot, or increase loot production by 10-50X in our generators. They cut wall prices by 10X, they can increase loot generation.
They really need to quit being so cute. Make conflicts more fair. For instance, have flat awards for everyone. You hit a base at your level, you get 500/300/100 for 3/2/1 stars. Attack up a level, it's 600/360/120. It goes up more for attacking more levels up, and goes down more for attacking more levels down. All bases should be rated equally at each hq level. They are now reaping the consequences of their short sighted matchmaking and rewards schemes. They can increase the rewards as you level up, because cook times become longer, and you can't attack as often. They really need to simplify things, and actually reward you for developing your base instead of screwing you.
The biggest problem Disney had was that they operated on a bait-and-switch philosophy. They'd give us something good, then screw us the next time. Zynga has got to stop treating us like total rubes and schmucks if they want this to last. I think the rubes may be done after they spent $100-150 per prestige building upgrade so they could jump to the top of the medals list, only to have their medals stolen. Like I say, I think some of those rubes may be done, lol.
