Awesome build I see you have built. Maybe I might make an arena build that uses fire/shock + bleed as a new concept instead of plain fire and bleed. Hopefully I could master it and deal much more dmg. First I will test it in campaign then arena.
Shock is pretty good in arena right now but it needs something like a buff maybe. So far I never seen a build where it used both fire/shock with bleed at once. Not sure what style I would do it but its worth a try.
It might sound op but it probably take more slots or skill to master then see in meta.
Ofc wizard is what I will do it as because amplify and other cool talents as well as other affixes.
Also there was this idea @cronos4321 mentioned where bleed chance is equal to deadly strike chance and adds to deadly strike chance. Its more powerful than fire bleed option but it encourage them to choose options. The bleed chance deadly strike option is more powerful but it take more slots. This is to discourage players using coat all the time and try different options.
That feature suggestion by @cronos4321 sounds good.
Secondly ,he mentioned how bleed should deal 500% dmg over 10 seconds (50% dot dmg per second) instead of 1000% over 10 seconds as a suggestion to balance bleed dmg so players can survive the bleed a little longer and have better chance to counter attack. Both those suggestion sound really good.
Another idea he had was: instead of 80% dot in 2 seconds of fire dot, make it deal 25% dmg per second (100% over 5 seconds dot). It isn't really a nerf but dmg isnt as big before and would help player maintain hp and provide counter attack.
