#sport climbing

i was at the crag yesterday, saw a route that was 5.14a but felt more like 5.13c tbh... anyone else think the grading is off or am i just overthinking it?? i saw a few climbers doing it in a half hour, which feels way too fast for a 5.14a i guess. also, some people say the grading scale is just a marketing tool, not a real measurement. so what's the deal? do we need a stricter grading system or is it fine as is??
