This is a melee-focused build for [Octavia]. The rank of the gladiator mods is irrelevant as they are only there for the set bonus.
[Enemy Radar] is more important than you think, as it gives you the information on where to go to keep your kills per minute as high as possible.
to take this build to level cap it is almost mandatory to have arcane energize to deal with energy leaches.
Roar is there for its bane damage, to scale your melee slash or toxin procs, at the 73% roar your status damage is increased by ~199%
if you cant [Reach] the attack speed cap after berserker for your frame rate with melee mods and strike then you can infuse warcry, and depending on the melee you could drop strike for a damage arcane (attack speed cap is between 3.5-3.75 at 150 fps)
you could also infuse eclipse however the damage isn't reliable even with the new light rendering.
