Take your time and have fun. MOBAS are not a kind of game you can master in a few hours. Take your time learn the basics of the game, worry about learning what abilities to level after that, then once you are comfortable then turn off auto buy and really start to learn how the items work and interact with the various kits. I recommend selecting a small handful of gods to learn the game with and stick to them for a while, so you don't have to learn a whole new kit every other game.
If you really want to develop at a fast pace check out some of the amazing Smite content creators that are out there and learn from them.

With the current roster it has to be Loki. The speed from his Vanish and his ability to one shot just feels great as someone who want to be active all across the map like myself. The new reset on kill added to his Vanish was a nice touch that really helps with quick escapes or to help chain kills
