Why would that be an issue?Apart from all this the biggest issue is that ranked ladder at pro level is completely dead and most of the top pros have not been streaming aoe2 for almost a month now
They can stream whatever game they want.
There is something casual players and viewers don't seem to grasp, is how exciting an entirely new game that builds on foundations you have acquired before is. Not only is the meta still changing every day, but AoE 2 pros face pros from other games who bring their own specific approach to the game too. For people who like competition this is a hard to pass opportunity.
