Why did GF even create Mega Evolutions? I understand the potential of giving fully-evolved third stage Pokemon Mega Evolutions but why do it with it Pokemon that are fully evolved at stage 2? Instead of adding a new evo to a line which was able to have one added such as Lucario, Medicham, Scizor, etc. they just give them a Mega Evolution and limit us to one per team. Instead of being able to use evolutions of two stage Pokemon we previously liked we are forced to choose one to carry around. I just feel like Mega Evolution just don't feel right or like a cop out. What are your guys opinions?

>tl;dr What was the point of giving Mega evos to fully evolved two stage when they could have gotten a normal evo added?
