It’s an interesting question for @kelr0nd and the other users who contribute to these…are we only considering OP10 in top gear or are we putting considerations into leveling…I guess leveling is too broad maybe and let’s just say UVHM, because pretty much anything works up till that point…
For example, the Shadow Ninja COM and Leg Hunter can very useful for leveling melee Zer0’s so I think it would be worth an aside under the Leg Ninja COM or in the honorable mention section for melee Zer0 (Leg Hunter should be in the top gear for gun Zer0 or at least HM there).
A question for all regarding the Punch-ee and Hide, what’s the max delay on each…I thought the max delay on the Punchee was enough to make
it useable while leveling, just that most versions have a delay that’s far too short to be of real use for melee Zer0. Similarly, the Law+Order combo would at least make HM if we were considering leveling, but then again, I didn’t find it much use for leveling my melee Zer0 and went with a bladed slag rubi instead till max level…
I ask because I can see some people would be looking for top gear to help them level and not just play at max level, or on the other hand, it could make the list too cluttered as a ton of stuff could be put in as useful for leveling…
I was talking to @Sun_Tsunami after the level cap increase and he said it was his understanding that the new OP10 combo for melee Zer0 involved an OP1 shock bone and OP7 Chain Lightning to strip an OP10 Hide, as that prevented downing yourself. As someone who can’t survive with melee Zer0 at OP10, I’m not qualified myself to discuss that further beyond passing that info along. If the above is true, would be worth making a note of that in the melee Zer0 section I think just under the respective items (“at OP10 this is the preferred version”) or something like that…I don’t have more info on Storm Front or other potential shield strippers…
I would remove the Fremington’s Edge as well, but then again, I don’t play Sniper Zer0 so was hoping to hear from some on that point 
I don’t know if Florentine is TG for gun Zer0, as a Maya player, I would have as HM for her or TG, but it’s probably best not to revive that debate of whether it’s any good, again would love to hear from the hybrid and gun Zer0 players on that one
