Except that's completely wrong! High AD scaling on abilities means you DON'T want BotRK, because it only gives 40 AD compared to up to 100 on BT.

As for attack speed steroids - sure they scale BotRK... but they scale BT equally! That is, if I have 40% attack speed, that increases the worth of both BotRK and BT by 40%. Their relative value doesn't change at all.

Basically, we have two approximately equal items - BT and BotRK. They are similar, but one is slightly better in some situations, the other slightly better in others. BUT THEN, there's a whole statistic, an entire category of items and effects, that affects one but not the other. Even putting aside balance issues, it's really ****ty design. All the auto attack stats and items reliably and intuitively multiply each other's power - except BotRK, which, let's face it, almost nobody builds EVEN when everyone is stacking HP! We're basically living in the ideal meta for BotRK and still nobody wants to build it because it loses literally over half its power by not scaling at all with crit!

Actually, high AD ratios would refer to champions like Garen, Riven, and Khazix whose ratios are so high that you can instagib people if you stack enough AD. You cannot do this on the champions I listed previously, they are autoattacking bruisers with small AD ratios.

You are correct that BT is stronger with crit, but if you don't build crit and you only want a single damage item, you get BotRK because it gives you sustain and an amazing active for bruisers. Yes, BT does more damage than BotRK on low-health targets, but when you dive a squishy on Jax, you will already have enough damage, all you need is the targeted slow/speed buff and enough sustain to heal back up (by attacking the tanks) after you kill the squishy. BotRK is a utility item for autoattacking bruisers that want the cutlass and need it to scale into late-game, it's not a replacement for bloodthirster.

the only situation i've seen it being better then a BT outside of the obvious slow utility from the activate is that it allows quite a few number of champions to solo baron.
