Legios is a good option, when you have enough resources invest praetorians, and for your defense make both. ++ Dont forget make imperians for your assaults. i think for start can do that.
This sounds like a recipe for disaster to me. Ask any experienced player what he thinks when he sees such an army - a few of this type, a few of that type and a few of another. When it comes to upgrading that's 3 different troop types to upgrade. While all three are around level 8 or 9, my troops are at 20, all backed by the hero's weapon, whereas only a third of yours are. Bad, bad strategy.
Legions, Legions, Legions in your first village at the start. And then EIs for raiding.
What you do next depends on lots of factors, but I wouldn't build Praets in my first village. Legions are decent in both attack and defence. You can switch to Imperians later if you don't need the def. Build the Praets (and the Scouts) somewhere(s) else. Defence village should concentrate on one troop (or maybe one infantry, one cavalry).
