The only reason Volkner's team was like that was because of the lack of Electric and Fire Types in Sinnoh before the National Dex which was fixed in Platinum. They probably want to keep it as easy and simple as possible for the younger players.

Everyone on this board loves to quip, "It's for the children", every time an idea comes about involving balancing NPC teams, making the game less linear, etc. Isn't it great to be able to discern GF's audience for these games out of absolutely nothing?
On the subject of Plat., why Cynthia got one of the most balanced teams of any NPC trainer, while a gym battle with free healing beforehand was "fixed" to have Electric-types across the board for "younger players", is beyond me.
