doesnt’ change the skill mechanic/effect or interaction, just what bonus dmg it scales on.
If you turn it to scale rata only it doesnt’ become more useful, but less (retal builds exclusively), and at the same time whether it becomes busted, ok or bad purely depends on the rata amount - in which case rata modifiers could just be added as is or to retal build items (but who wants to play a retal box/the way Box works mechanically 
)
*i don’t remember if the net was an actual/true secondary effect or not, (been a while since i tested to confirm interaction), just that some modifiers don’t apply to the net as mentioned. So if that applies to regular dmg mods and not just RR mods, it would also just make it still useless to boost on items/rata.
**i wouldnt’ want it changed to a trap skill simply because they suck/i don’t want more OFF/BT/CC skills in the game personally. But i also don’t want it to be just a sigil or aura because those are inherently boring also. - i just don’t know how the heck to tweak box to make it functional for endgame, when it can’t be tweaked on raw numbers alone, and it should remain "effect"wise fun imo.(which i think its “net”+tether is)
i don’t see it as DB at all, but a debuff skill/war cry because of DR amount and uptime, the wd/dmg is just a side bonus. Same DR as war cry, better uptime/matches CD wise, same aoe style application. If the DR or confuse wasn’t there, i wonder if anyone would ever have taken it outside that “1” rimetongue? meme build
