That's true, but that also just illustrates why doesn't really work as a universal starting jungler item: the +10 AD against jungle monsters sort of works because everyone autoattacks, but heavily favors champions who naturally do well with AD, i.e. AD autoattackers and casters. To make the most of this, mages and tanks would have to build attack speed, a stat that has no use to them at any other point in the game, save for their first clear.

The +5 damage reduction from monsters is also good, but the problem to both this and the above passive is that both are lost once you upgrade to the next jungler item. The upgrades are stronger, so there's no decrease in power, but it would make a lot more sense for each item line to start with its own base component that didn't cause any loss in stats, rather than to start from one universal item and awkwardly transition from there.
