I do totally agree with the need of evolution side, but to me the pvp strategic aspect does not matter for most players, it represents a huge amount of work (many pokes, many moveset/nature for each of them, frequent updates about this), so better to keep it out of the game.
Still, details about evolutions in pokedex is great :D
I also suggest while we're talking bout pokedex a checkbox to show only the pokes and the stats (caught, seen, evolved) for each region !
