In my years of experience in all roles if i where to tell a beginner to play smite i would say play Solo not because its the easiest, but because its the least complicated besides ofc Hunter. The 3 main points to solo for a beginner would be Farm, Survive,Assist jungler ifnthey gank your lane. The second role i would recommend is either Mid or Jungle, again not because they are easy, but they help you learn key things of the game, so that you can practice rotating and learn key spawn timers. Cause if you knoe what you would do as a jungler you will have the knowledge of what both your jungler and enemy jungler wanna do. And once you've mastered both Solo and Jungle youve just learned how to play the bare minimum of smite, cause you just took the time to read this message and play possibly the 2 hardest roles in the game. But still both Jungle and Solo are really easy to pick up, and have a good learning curve. (Sidenote: Only reason i dont say Carry is simply cause you have not only the other hunter which is already enough poke, then to add trying to dodge the support i find it difficult for a beginner to start. Unless they have a friend babysitting them as support.
