AD ratios haven't been gutted, they've been moved to sustained damage.

You are undervaluing penetration, however; I'm assuming you're not including his base AD as you would for other abilities when considering base vs scaling. Q's base becomes 283 with 120% AD scaling, and empowered becomes 384.2 with 130% AD scaling at 18 plus the 250/340 from E.

Fervor is amazing on rengar, though. initiating with an ability and getting 3 auto resets gets you 296 damage. Would be higher if not for the recent nerf. plus 111 for almost every hit after. which is also another number that doesn't scale with crit or AD, increasing the value of armour pen. thunderlords gets you... 180? Nope. I'd fervor every day.

He has counter synergy with AS, though so long as you're using empowered Q. he has 150% extra attack speed at max level. that means you have to divide whatever AS you get by 2.5 if you want the actual damage % increase number it grants you - and that's only for DPS, not upfront damage which is still his primary strength.

Battering blows is generally worse than precision. 47. 14  - 120 (based on level)    is the amount of armour required to break even. precision, however, also includes your spell damage, which you still do if only a tiny amount. large portions of the game your average target will be under that.

Rengar scales into the lategame about as well as a master yi. and if master yi wasn't melee, he'd be the strongest adc in the game. Practically the only downside to rengar is that he's all-in. up to 105 extra resistances for free causes all kinds of problems, and basically increases the value of his health and lifsteal by roughly 50% depending on whether he's already built resistances or scaled it up early. This is what lets him function as a fighter. it's also why titanic hydra is ridiculously frustrating on him since the effective health it grants with max roar is 1350 health, every Q procs it for 30 extra damage, and even grants an extra AA reset for 250 extra damage.
