Rambling Of The New Year
It was (I think) the first in the series of Do-X updates (like Fletch-X, Smelt-X, Spin-X, etc.) that took out some of the repetitive clicking from the game. While I certainly wouldn't say these sort of updates "ruined" the game, or even any individual skill, perhaps they were still the beginnings of a lazy, impatient attitude towards the game that would really become apparent starting in the late 2000s, as well as in Old School RuneScape as a whole — the "quality of life" updates that the EasyScapers push at every turn.
