>>33271185I've never used a legendary as part of my playthough team. Don't include me in your newb/noobish ways.
Even when the newer games force their capture for a battle, I just let them faint in the forced battle following that off the bat.
I've rarely even used them in PvP, let alone in-game. And even then it was mostly to specifically take on a threat. Started using Regirock as an answer to Talonflame last Gen, for example. Elvis the (Mega) Gallade and Jesse the Regirock were a pretty good pair in OR/AS.
Now, I did just use my starter for every main playthrough alongside an HM user or two up until X/Y when the wild diversity and Exp Share changes were just too good to not use a full team (more than a full team actually, as I had 13 Pokémon on my main X team, lol) but even that's different from what you're implying. I CHOSE to solo run them because it was simpler. It wasn't because I didn't think about having a team, it was just a waste of time.
Why take 20 hours trying to grind out a team when I could steamroll Red with the starter (meaning all items obtained/all trainers beaten) in less than 6 hours? Made no sense. Teams were clearly for after everything else was done when I was equipped to make proper use of them since I had all items and locations open to me.
