BUT - if you want to just have a historical game or to win the victory conditions, it is a waste of effort to take over the steppe. Yes, sometimes the nomads expand into Europe like they historically did, but I almost always see them evaporate to their previous settlements on the steppe in a few decades. If I wanted to just kill everybody and rule the campaign map, I would probably be able to win in a few decades, but it isn't too much in the scheme of a long game played semi-historically.
Remember that armies are limited to a few, you will need some to defend your homelands in the Mediterranean and more to fend off other possible enemies or revolts. It is good then to not have to worry about the horse nomads, who can with a bit of luck on the AI's part wipe out a few of your stacks in ambushes or sieges even if you spend 20 minutes in field battles waiting for arrows to run out and win all of those. For the cost of a few armies you can send the horde's other enemies some gold and pay the horde for peace. The horde will likely be busy with other enemies if you keep funding them, allowing you to avoid a redeclaration of war.
If you want to fight them, yes, you want to use cavalry and missile infantry with a small core of legions to hold shields in testudo and absorb a million arrows. Slingers AND archers are good, but slingers come out ahead on the steppe with longer range and better projectiles so long as you protect them with your own cavalry.
