Mine in Emerald was a level 60 Blaziken, level 30 Swellow, level 20 Azumarill, and 3 other Pokemon.
Also, how long did it take you to make a well balanced team in terms of levels and a bit of strategy (With team levels within around a range of 5)? My first one would honestly have to be Black 2, last year.
Which is pathetic considering I'm 15 and I've played for nearly 8 years.
If your future self hasn't come back in time to tell you not to do it... Then it's not a bad decision...
I learned how to create a well-balanced team by playing Pokémon Yellow. The implied team in that game consists of Pikachu, Venusaur, Charizard and Blastoise (I know many people don't use that roster, but I do). Using those four and then filling in the blanks strategically helped me to become a more effective Trainer.
I don't remember my first team at all. Was too long ago for me to remember.
But I've always kept a balance of levels / pokemon types in my teams, even at the beginning. I always wanted 6 pokemon and not just one super-strong one (because the variety was one of the big things that drew me to pokemon in the first place), and never wanted to use all of one type.
The only "bad" thing I did at the beginning was the typical "all same type attacks" thing. Ya know, the Blastoise with all Water attacks, Electabuzz with all electric attacks, ect.

First team ever was Venusaur, Wigglytuff, Hypno, Farfetch'd, Seadra and Aerodactyl. Not horrendous by any means, but the movesets were pretty dire. I've still got the same file to this day, although I've revamped their movesets several times.
