I suppose 100-75 for TPvP is fair. It's a large event with best of 5 and double elimination, which ensures that the winning teams are very skilled and the best teams are very close to the top. This gives a total of 525 points handed out. For such a large and important event, I suppose this is fair.
However, 75-50 stills sounds too high for events like HPvP and the first two drafts, which have teams of 7-8 players. With 75-50 for HPvP, a total of 950 points are awarded. That sounds a little high, when events like Sideboard is 400. Do you believe HPvP is more than twice as important as Sideboard? Is it more than twice as important as Sacrifice?
Lastly, I still insist that Falling Empire should be an individual event. My impression from playing in the event was that it was essentially every man for himself, and I feel like that's what The Mormegil intended.
