The % based mastery's that increase/decrease damage are useless, in my opinion. For rank 3 havoc, you have to deal 1000 damage to get a bonus 15. It's negligible on ad carries who would be doing ~1000 damage in the first place, and impractical on ap carries who can't deal 1000+ damage efficiently. And even then, a nunu ult doing 2000 damage would only give 30 bonus. Executioner + Havoc would give 75 bonus damage at 1000 base IF they are below 40% hp. While you may think of situations where you survive or the opponent survives with 20 hp... the frequency of these are low enough that it may be better to not put yourself in them in the first place. Play smarter than your opponent and you can guarantee your kill, not put everything on cooldown and hope for the best.
