T1 should quit making sudden and drastic comp changes.
The two that will perform less well with that change are iZu and Meteor.
Buzz, Meteor and iZu are basically the top 3 firepower in T1.
If two of them are underperforming, Map, which should win, will not win.
I can't say for sure that T1 would have won Split in a traditional Comp, but I think they would have fought the good fight better than they did today.
