I played it right from the get-go, anon. Bought that special collectors box that had the three original core books and me and my group played 4e until well after the release of 5e. We never had issues with it and the only tweak we did was just have a homebrew rule that you could use an action point to use an already used encounter power or two action points to use an already used daily power. That was basically it. Even after MM3 and the MV, we used the new math but felt no real difference in terms of combat and stuff.
