Because if players aren't happy to buy sub and make the micro transactions -the game will not have funds to survive and many of ppls wich are talented and dedicated -will loose their jobs.
The game wasn't casual enough for the new players and guess what ,now Wildstar lost tones of ppl : .Imho ,the same thing happens here too,in a very very close future. This game its agonizing and loosing players day bay day.Some are leaving beacuse they feel unsatisfied of rng ,some because of grinding ,they are enough many posts in here telling in fact the ppls got enough if it ,most of them going away because of the poor optimisation and support.To draw (again) a parralel between Wildstar and BnS: the wildstar had same kind of stuffs tho they tried hard ,the game were less grind-ish and much more optimised,had way more content then BnS and were posibile to buy sub with in game moneys.Yet the game were full of bugs and many players left after the contracts table were reseted times in row ofer and over again ,when you dc'd in a dungeon on last boss and you would get absolutely no loot after hours struggling.
