Yes, OW divers need dives and experience before they task load in a rescue situation.
Rescue class is appropriately placed after OW and AOW. AOW is a joke. I'm a PADI certified DM, and for the life of me could not figure out what AOW helps you with besides a few navigational skills. I read all the material, some of it supplementary, interesting boat terms. What did it teach me as a diver? Well, I had about 40 dives at that point, was getting the hang of things and took AOW. I see watching the OW student that jumps into AOW, or the OW student that didn't dive for two years take AOW, how AOW is meaningful. It's a safety stop before Rescue. This is my conclusion. AOW reintroduces divers to diving in a safe way, a little more than a review, so as not to bore divers that dive flat out. Also, divers that continue to AOW, are showing an interest in furthering their knowledge. They might actually invest enough to take rescue class at this point. They realize more training is needed, but yes, AOW is a dull class. It's really a safety stop to ensure everyone has a certain amount of experience and has checked in as following procedures.
Now, Rescue should not be taught in conjunction with OW, because it would be a LESS effective class were it taught to someone completely new to diving. Lets not forget we at one point knew nothing about diving. It was a way to go underwater and we didn't know how it worked. OW is a handful. Divers should cautiously dive after OW. They laugh at the 60ft max dive limit PADI recommends, because they think they're full divers. They have beginners licenses is all. I got my driver's license and didn't touch a car for a year. Did that make me a good driver? No, I crashed my work's van and totalled the car in front of me and damaged the car in front of them. The AOW "allows" you to dive to the full rec limit of 130', because you have some experience at this point.
Some people take the OW class, go to the Caribbean for a week and that's it. People deserve their freedom of choice. Should they choose to only take OW, they are aware of the risks. They sign waivers, are told of the dangers, and don't care often until they need something to blame for an accident. Some people know it is better to invest, be smart, research. As I said in another thread, get in your pool, look at your gear, try it on, check out rental gear, ask questions, dive in the lake with a DM, take a refresher, breathe up a tank just to see how it feels on the surface, take our free Dive Training Magazines. I think people should choose the program for them. DIR may be good for some people, putting people through extended training, but others may want a different approach. PADI worked well for me. I pick up on information quickly and ask LOTS of questions. I wanted my freedom, and I wanted to learn for myself. I don't react well to bullying or do this or that.
Anyhow, I agree with the order in which Rescue is taught. It isn't for everyone. Here's an example of someone that refuses more training: My dad. He has a DM for a daughter and refuses to even go diving in the pool before he takes his Caribbean trip for the first time in 10 years. The last one was with me, and it didn't go well either. He left me 200 yds after bleeding off some of my air because a 14 yr old girl doesn't breath a lot of air. I was in an OOA situation, and did a normal ascent w/o training. 15 min later, he finally surfaces and then realizes I'd been at the surface, not caring one way or the other. So, during his Caribbean trip, his 15 yr old fins snap, the DM lends him fins, he's terribly overweighted, his wetsuit chokes his neck, he didn't rinse his new mask with toothpaste and it fogs incessantly so he can't see the entire time, and he says it's his best diver ever. Go figure That would have been my absolute worst dive. He even complained that they made him take a DM, and with his umpteen yr old OW cert boasts of "cave" dives he used to make. Sounds outrageous huh? His choice. He's been told.
