What makes u think discharge will be a better pick than overload? You said this build is based around melee and I agree but I have my own build in mind...if you are basing your build of off gear such as helm if Inmost light then rainbows are not going to be near as crucial for a storm fist build as u made it sound like....nor will it make transfusion and discharge that much better...as a matter if fact it won't help any of them Storm fist is a a melee that deals bonus damage....Transfusion procs off of storm fist and has a chance to immediately trigger health regeneration when killing an enemy with storm fist....discharge procs off of storm fist and has a chance to deal AOE damage when getting a kill with storm fist ....overload has a chance to immediately reset the cool down of storm fist....helm of inmost light increases your melee attack speed but it's not helping storm fist if it's on cool down...and nothing procs off of melee...it procs off of storm fist melee So to the most viable striker class...you will have to choose between transfusion or discharge....because u need to keep overload on otherwise they are a one use ability unless u live long enough to use them again and even then it makes them way less viable.....for example let's say you are using transfusion and discharge with helm of inmost light like you said....you run up on an enemy and punch him with storm fist your transfusion procs so u have health regeneration and so does discharge aoe u have AOE damage now too....but helm of inmost light doesn't really help anything because ur storm fist is now on cool down so you have increased melee speed for virtually no reason considering the fact that it's not going to help proc any abilities since it can't...so the only thing you have left yourself with is a plain Jane melee attack with no benefits of using it except base damage So imagine I'm using storm fist with overload and transfusion but since I'm using overload I'm not using discharge.....I run in and hip fire a guy lowering his health and then punch him with storm fist and kill him then I immediately trigger health regeneration and overload procs and I immediately reset my cool down for storm fist again so I can punch the second guy kill him and have a chance to trigger health regeneration again as well as my storm fist cool down....and with rainblows from my helm of inmost light I'm now (if they proc) virtually resetting storm fist instantly back to back to back and therefore resetting transfusion instantly back to back to back increasing my health regeneration and survivability through the roof....discharge is bit nearly as viable tho considering you can't use that and overload at the same time unless you get the ability from a piece of gear. So to be honest I think your build is good but not nearly as viable as mine is
