User blog comment:Lukeatlook/Pyro's Item Overhaul 4 - Welcome To The Jungle/@comment-10764129-20140412042704/@comment-4813965-20140412095933

As I said, numbers can be fixed. Keep in mind that it's 1% per second, so with properly adjusted fadeout time of the buff will regenerate over 100% of a jungler's HP over two minutes. For comparison, 4 health potions regenerate 600 HP, which is close to tank's health pool at level 2/3. This is so huge that the item could actually get a price increase to 440.

AD junglers who prefer building tanky, Vi for example, often do possess AD ratios on their spells. I'm having a hard time naming a single jungler using SotEL right now who wouldn't benefit from the spell damage amplification on a starting item right away. The lack of AA enhancement against monsters on a finished Spirit item is a tradeoff for a better early power witht he Spirit Stone. Anyway, clearing jungle with the finished Spirirt item wil hardly be a problem, even if a little bit slower than before.
