I do agree that the combat system feels lackluster. I don't like this left click, right click combination combos its doing. At least not the way it is right now, its very hard to know where in the combo you are, as it all looks the same. (coming from someone who went 3 times to lvl like 9 or so, so not familiar with higher lvls. I can only voice an opinion on what I've experienced right?)
The dragons seem very similar to the pets in wow except that you can ride them, they don't do much more. They don't feel like your main asset tbh.
