I full-heartedly agree with H3ENnZ and Laundry... it is NOT a good idea to go pro, because there's a very low chance you make it into tier 1, and even if you do, it's only a viable profession until you're in your early 30s at the latest, at which time you'd have to do something else entirely.
HOWEVER, if you are completely dead-set on this idea, then here's my take on how you can get there:
- Climb to radiant (or at the very least immortal 3)
- Form a premier team with other radiants
- Win premier
- Make it into Challengers (tier 2)
- Perform very well (this may help you get noticed by tier 1 teams, but even if you get here, nothing is guaranteed)
- Receive offers from orgs if you're good enough
(Note: alternatively, your team could go on to win Ascension, which would also get you into tier 1 if your org decides to keep you or if another tier 1 team thinks you're good and buys you out)
- Profit (well, some profit, anyway... wages differ depending on the org, but if you're first heading into tier 1, then you're not going to be worth very much)
Good luck with whatever you decide to do with your future. 🫡
