Before I say anything else, let me be clear about one thing. This game IS good for someone who is new to MOBAs. Playing around on it can be fun, and you can have a good time just pounding on the computers if you want. I like the way that you can mix the activatable abilities of your dragon by swapping in different weapons. It's a feature I haven't seen in the other MOBAs I have played. The weapons usually don't provide abilities that are broken with any specific dragons, so the balancing on it isn't too bad.
However, if you are familiar with MOBAs, you'll only really play this one when you don't have access to your favorites. The monetization of this game leaves a lot to be desired. I get that they are trying to make money off of their product, but they didn't have to make it into some sort of CCG for dragons and weapons. It's nice that they provide a daily login bonus, and that every 5 days you get another free (random) dragon, but the amount of gems that it takes to get the booster pack of dragons or weapons is pretty high, and you don't even have the option of picking out a specific one of either. They love to point out how many gems you would have earned after each match if you had just been willing to spend the money on a Titan Pass, too, which I find to be very annoying.
All in all, this game shows a lot of potential, but it's just not living up to it for those of us who are already familiar with MOBAs.
