Strength Copy Woes

I tried to create a strength copy and it was an utter failure. They have no jutsu that are reliable for strength at all. One of the jutsus they could have relied on, Falcon drop does about the damage of a punch with 40 strength, I wanted to throw my computer lol. Twin weapon barrage did barely anything as well, and that's on top of the fact that raiden is a lot weaker without nin. I don't wanna keep complaining so ill just suggest:

Add a few more strength jutsus, maybe borrow a few from tai specialist and what-not. Buff the ones that I mentioned that are already there, and give them a strength ultimate, something to compare to DS. This would certainly not make them oped, they have a long long way to go for that to happen.

Rasengan is str based btw and i agree dante could Aadd dynamic entry or primary lotus and as for a str ult
Summoning Jutsu - Ninken Unbound- summons 4 ninja dogs that targets 1 person attacking and cause target to bleed also applying a 5 sec slow

That sounds kinda interesting though, I don't think rasengan in reliable, it doesn't hit unless you got snake bind on them. Idk for a fact though, I didn't use it. This is just from what I heard.

Never used copy ninja, but I do know the jutsus they can select, and you're right, there don't seem to be many attack power-based options. Would make sense to throw in primary lotus or something.

A long time ago I saw a strength copy use Rasengan in the same way you described - while someone was binded. Not sure how much damage it really does, though.
