I have cold Blade Arc Blademaster.
There is also Pierce spam PB Blademaster somewhere on the forums.
Melee Spellbinder is garbage. I have checked couple of patches ago. Full Krieg, like crazy flat numbers, but it could barely squeeze in 8-8:30 in pre-1.1.4.0 Crucible. It wasn’t dying tho, due to all fail-safes, but damage was depressing.
