Exp can now be gained by capturing a Pokemon...nice for catching sprees I guess.
its really nice anyway, though? i dont know about you but when im training on victory road or something and i find a rare pokemon, i both was the exp from defeating it and i want it in my pokedex.
plus, the new exp share mechanic is really nice. it saves a lot of frustration when training, decided who to give the share to and who to fight. now it doesn't really matter who fights, everyone in the team gets a share from watching.
