Im afraid this is gonna make the entrance to pvp even harder. Imagine having to grind for several months just to get viable units in starcraft, and then if u wanna switch from terran to protos you had to grind for another 3-4 months. Im afraid this is going to hurt the longevity of the game. It is an RTS after all. As a completely new player you won't even know if the deck ur going for is the one that feels good to play for u. And you cant try one out either. Slowing down the progression might be good for people who enjoy the PVE, but it might ruin the game completely for some or allot people
