I guess LC is too much of a hard tier to play with. I mean, look at OU with its Ferrothorn and Infernape and all that Pokemon. Players sometimes are enticed to play with those kind of Pokemon rather than their pre-evos. (except for Eviolite Chansey, who is better played with than Blissey). And EV training without going up the level barrier is too hard. You will be running around killing Bidoofs and such.
