I like where the Qarthians asked to see her dragons, a pretty reasonable request given there hasn't been a dragon in hundreds of years and it's virtually impossible for one to have come back, and she completely refused for basically no reason. Then when they made it clear they would leave her to die if she didn't, did she say, "Ah wait! Ok, I'll show you."? No, instead she went on a massive rant on how she was going to burn Qarth to the ground and kill them all. What a genius diplomat. Only by pure luck on her part did she get into Qarth, and even then it was just so that Summer Islander could take advantage of her dragons and become King of Qarth.
After she crushes the Yunkai in the field, does she go into the city to show them what happens when you disobey the Dragon? Nope, why the

would you do that? Let's just make these brutal slavers give their word not to go back to slaving. Genius. Can't even believe why they would go back to slaving as soon as she leaves.
Then, the Qarthians begin blockading her in Meereen. Well that's ok, I mean she's got three massive Dragons that spew fire so hot that they can melt stone. She'll definitely use her dragons to stop the blockade and save her people from starvation... Oh wait,

that

. Some peasant girl got eaten once, so let's just lock our dragons up in a pit (which she

ing knows will make them smaller and less powerful than otherwise) and let them chill. Let's just chill and let our people starve while Dany goes and eats expensive foods, gets married, and all that cool stuff.
The Astapori are infected with the flux, a disease that has wiped out entire armies and doomed Kingdoms? Let's let them into the city.
Remember when she hears from the Butcher King's envoy about how the Yunkai are training massive armies, all these slaver cities are mobilizing, they're get a bloody Khalasar to come, etc. ? Remember what a great and genius strategy used to fix these problems? No, you don't because she

ing did nothing. Holy

, I know the Butcher King sucks and all, but he's not as bad as the Wise Masters.
My Dragons are born. Will I go back to that holy Dothraki city (I forget what it's called) and use them to convince some Dothraki to join a make-shift Khalasar?

that. Red Waste here I come! She doesn't even have a plan to get by the Red Waste. She just walks into it. Also I know there were like 20,000 Dothraki in her way or something, but she only has like 20 followers. She could sneak past that. Hell, safer bet than the Red Waste.
I've completely destroyed Meereen's only source of income and need to return it to greatness. What will I do? Why, I'll grow beans and olives, of course!
She really doesn't seem a master strategist either. All her opponents had no idea what they were doing. The Yunkai outnumbered her and knew her dragons couldn't do much. Would they attack after making the offer (when she would presumably be unsuspecting of an attack)? Nah, they'll dick around outside the walls. Meereen should've done something like, I don't know, put a bloody grate on the sewage pipe. This is almost as bad as the Death Star. A bloody 50 dollar grate. Go to

ing Meereen Mart and buy a

ing grate you
