Let be honest here. Sasuke S/T Jutsu is not as bad as people make it out to be..
Sasuke's jutsu
CONS
- cool down time.
- short- medium teleportation range limit.
- medium-long range shifting jutsu.
FTG
CONS
-Prep time
- need seals to work
- can only teleport to seal location
PROS.
- No prep time.
- doesn't need seals.
- can teleport to any area within range.
- can swap with people and objects within range.
PROS
-no cool down time
- no range limit
- Can instantly teleport from seal to seal
- Can teleport huge projectiles
I left out small details like Sasuke can teleport to a moving object or person, and Mina can teleport to a moving seal because it basically the same...
One thing important to mention is that Sasuke's jutsu still have some uncertainties (pros and cons), while harishin have shown everything..
It all comes down to preference.. The way I see it is if you're fighting a smart powerful ninja, then I would chose Sasuke's jutsu... If you're fighting multiple strong enemies, then I would chose Harishin..
Preference is the key, so let's just stop hating on both sides lol
