Well I don't expect anyone to understand this, but SOME people do like the "grind". Some people do like goals, acheivements that add to their gaming experience and stay. Most of these players already fled this mod in January (still the biggest "whine" this forum ever knew), when basically high levels were shot in the back.
Removing all the grind will feel like Native. You fight a round, then bam. You fight the next and nothing changed. You didn't constructed anything. There's no challenge of reaching something, because there is nothing to reach, no pleasure by frustration and satisfaction, because you have everything instantly, no feeling of "work well done", because there's nothing difficult to do anyway.
