As longs mechanics stay the same then sure, they could adjust difficulty down for newbies to test out and get there feet wet. If that was the case I would use it as a training ground to learn what all is happening better that way I can actually prepare before a raid, and maybe just hop in and have fun with randos. I have done some raids, but I haven't done every mechanic in the raids I have done, usually I was told how to do what I needed to do for a particular encounter. If they add an explore it should be all about the learning pf mechanics and not about loot at all.
