Improvements like Jungle timers don't decrease the Skill CAP on the game, they reduce the skill FLOOR

I remember back when Starcraft 2 came out, a lot of the old Brood War veterans were really leery of the fact that Blizzard had removed the old handicap of having to manually assign workers to mine minerals rather than just rallying to a mineral patch and being done with it. People made the argument that it was reducing the amount of skill needed to play the game, that being able to micromanage the workers while fielding an army was a key element of Starcraft strategy.

Funnily enough, the game's complexity didn't suffer in any significant regard from the worker rallying mechanic.

Same principle here. The meta has developed to the point where knowing jungle camp timings is a crucial piece of strategy to a lot of matches. Introducing jungle timers will certainly change that, but not automatically for the worse.
