The problem being that when you get near the end of the game, the levels to evolve anything go through the roof. Here are the worst examples with the highest levels you can encounter their prevos in the wild in BW1. Keep in mind that the 8th gym tops out at a level 43 Haxorus, and Ghetsis' Hydreigon is level 54:
>Mandibuzz/Braviary - 54 (Prevo 39)>Bisharp - 52 (Prevo 39)>Golurk - 43 (Prevo 33)>Ferrothorn - 40 (Prevo 27)>Beheeyem - 42 (Prevo 29)>Eelektrik - 39 (Prevo 27, and it can only learn 4 fucking moves)>Fucking Lampent - 41(Prevo 29)>Mienshao - 50 (Prevo - 41 on V. Road)When you get shit like Excadrill at level 31, Darm at 35, Crustle at 34 and Gurdurr at 25 there's no reason to gimp your party for 10+ levels when what you were given mid-early game is so much easier to use.
As a fan of gen 5, including its Pokedex (starters excluded), this is the shit that pisses me off the most. So many cool options become available in the endgame, but the effort vs payoff is nowhere near worth it.
tl;dr: Evolution scaling is fucked, so by the time you hit midgame your team is set in stone.
