The pros are obviously faster rating gains and potentially getting access to gear you wouldn't otherwise have. Plus, you can learn a lot watching skilled players in action. The cons are the cost, of course, and the potential stigma some players attach to it. I've heard stories of people feeling like they haven't truly earned their rank, which can impact enjoyment. Maybe you could try watching some high-rated arena streams first? Some even use tools to analyze positioning and strategy. It's almost like seeing crazy cattle 3D, with everyone frantically moving around the map! It might give you some insights and save you some money. Good luck with your decision!
