The problem isn't that wolves GIVE that much, it's that it TAKES time away. By getting wolves before blue, you can shave about 15-20 seconds off of your jungle clear time. With people helping you damage the wolves, pretty much EVERY jungler is capable of clearing the wolf camp BEFORE blue spawns...so why not just get it first? True, it IS a choice, but it's considered (and statistically proven) more efficient to clear wolves first.

Second thing, smite less blue(or red sometimes). This is so that you can tank earlier if needed. Most jungles go wolves, blue, wraiths, golems, red, wraiths. This path will allow you to hit level 4. While you are leveling you tend to take spells that can help you clear camps. For example hecarim, at level 1 you get q, then level 2 you get w, then at level 3 (which is reached after killing small golems) you get q AGAIN for the damage and aoe clear. Finally after killing red and wraiths you will hit level 4, finally allowing you to get a point in e so you can gank. if you have to blow smite on blue initially, this will be the jungle path you go on. If you needed to gank earlier, you COULD, after getting level 3 at small golems, put a point in e and gank, however, you do not have red buff because you wouldn't be able to kill it without smite (BECAUSE YOU WILL DIE TO IT). With smiteless blues, you can go to wraiths after (assuming you took wolves before blue) then go straight for red and smite red. Now you would be level 3, have your ganking spell, AND be double buffed. Of course, not ALL junglers are like this but most are. Also, smiteless blues allow you to be more aggressive with early invades, if you have smite up, you can steal their red for example with ease.

Hopefully you took the time to read, sorry for grammar or sentence structure mistakes, I rushed it.
