I wonder why didn't we get any information on what tactics got buffed? It will probably take seasons to actually figure out if something like PtB got buffed, especially when there's quite a bit of random involved. Especially especially when we don't have any way to check the stats or win rates of certain tactics.
I doubt the bast teams with the best players will all of a sudden start playing II and OI 24/7, furthermore having PL's be the only real way to check things out, leaves non-supporter teams (that want to be competitive) wondering if things work or not.
