I'm not quite sure how the number of Pokémans affects the tediousness of breeding.
In fact, if we're correlating the two, there's surely an inverse proportionality.
I.e. In Gen II when breeding began, there were the fewest Pokémon to breed. Yet there was no Destiny Knot, Power Items, abilities like Flame Body etc.
To answer the orig question, having max IVs in the wild feels like a Soft Reset fest to me... But hey. I'm a curmudgeonly veteran, who has been breeding Pokes since the start.
In other words. It's your hack, so do whatever you prefer. You have the power :)
