While I agree it will open up competition for the top spot in each skill, it is very easy to become discouraged in training when the gap seems insurmountable. Take for instance, Fist of Guthix. The #1 ranked player has about 444k rating, the #5 ranked player has about 334k rating. In order for the #5 ranked player to compete for #1's spot, they'd have to gain 1/3 of their rating instantaneously before there would even be a competition. For a player starting out now, gaining 444k rating on the top spot is impossible, no reason to even try. One reason the #5 player might still be playing FoG right now is because they enjoy it, they need/want rewards, or they have a goal to reach a milestone rating (Like, 500k or 1M). I sincerely doubt its to be #1 in FoG.
