No one says getting advantage is bad. Its the lack of "opportunity" cost thats the problem. Like someone mentioned when "King of the Hill" battle is never wrong its becomes a boring requirment. When your Rogue sneaks into a ruin and find with perception a way to climb a pillar thats a viable spot for Advantage approved from a GM thats okay. You can use a athletic check to climb and thats the reward, a advantage position before starting a fight. Or a barbarian can use a strength check overturn a fire bowl to kill a bunch of goblins and create a ground effect. The GM interaction is important but its a "small" local effect and no general mechanic. Without Strength you cant overturn the fire bowl, without athletic you cant climb the pillar. But King of the Hill is easy and possible by all without requirments.
