Stage 2 playoffs give 1 point to the winning team or was it only for the group stage?
yes
you still get 1 point
so whoever qualifies thru circuit points is only determined after playoffs r finished?
yeah but tbf it's just one extra point, cuz if you win two matches in playoffs, you're basically in top 3 already (exception to the 1st and 2nd seed's bye, where they also got extra point, simulating a win in the single elim)
