I use price action and indicators in my trading. I have used them for 30 years, it still comes down to looking for patterns within price and looking for patterns within indicators. I believe most traders use indicators as they are written in books as in when X crosses Y, but if one looks "outside the box," indicators can offer small nuances that are much harder to see within price. If they were all taken away as far as indicators, sure I can trade and have to concentrate much harder, but I can sit several feet away and it just makes for a quicker identifier for me by using them.
I will agree though, most don't know how to use and only confuse. Just like taking a 20 EMA, so many will say if price above, trend is up and yet, this shows me nothing, as I look at it I take into consideration the speed of change, slope, mean reversion and time. If EMA is cutting thru center of most bars, many can't easily identify chop cause they are centered so close to each bar, they don't see the Forrest.
Another problem I see often is too many are trying to get the fastest indicators for reversals, that for most are just wasting time and money, too fast offers too many false patterns and too much overtrading. But using just price, same can happen in doing breakouts or breaking of pivots.
Indicators are like anything else, whether it is price, volume or a moving average, the more you study, the more you learn about relationships. And for me, blending of both just makes it easier for me, but watching many for such a long duration certainly has it's advantages.
