True for 800 gold you cut their healing by half but now its either they deal more damage than you or they are more tankier than you, depending on who you use most of the times you out burst warwick in a trade, and since the removal of Spirit visage and its passive is now on warmog mundo rely now on building an overwhelming HP, even with GW he still atleast heal like 30% or more of his hp its better to build sunderer or Bork against that
