Because Rengar's kit needs relatively less gold to function well, the stacked attackspeed plus the base damage and ratios scaling on TOTAL AD makes him a good damage dealer even without the need to buy many AD items at all, Bonetooth Necklace was enough to make him able to dish high amounts of damage for being built as a tank.

Meanwhile, if you don't buy any ad on regular assassin you won't get your damage further then your bases, plus you have nothing that can be used as a tool for your team if you aren't building damage.

Rengar's ult is enough good even without the stealth on Tankgar for the sole purpose of giving the true vision over a large area of the map.

He has also a snare and a slow.

Common assassins have just damage and mobility and sometimes soft cc like a slow of brief duration.
