Brawl is a hot, steaming turd. Period. There are almost more issues with it than I could hope to enumerate. It is unquestionably the worst thing to happen to RoB (yes, even worse than the new Gobber’s Duties).
Upgrading dragons is counterproductive. Token distribution is badly skewed. Dragons, especially the new ones, are badly skewed (I need as many tokens to upgrade a grade 6 heroic dragon as a grade 12 heroic dragon). Champions are utterly pointless because they are, and forever will be, several grades behind the rest of your roster.
That it’s rigged so that you can’t keep winning is the least of its problems. Honestly, I don’t understand why people get quite so worked up about this. It’s not like having to lose as often as you win (or, just, not play 100 times a day, because why would you want to do that anyway given all the other problems?) is that big a deal, or makes it impossible to go up in rankings. At an exactly 50% win/lose rate, you will gain 25 trophies every two battles and will always be facing off against opponents at (or even slightly below) your own level… which is a winnable fight more often than not.
I also don’t understand why so many players don’t seem to understand how turns work. Maybe it’s because they took out the ‘speed bars’ that showed how each dragon comes back up in the order. Maybe it’s because no one plays classic video game RPGs (Final Fantasy I, Crono Trigger, and the like) any more? I admit this would be less frustrating if there was some indication how it worked, rather than being a mystery to players that don’t understand the underlying mechanic.
