Yep, just look at what Minato did with just a few sealing techs. People tend to underestimate the power of sealing techs because it isn't flashy and destructive...
There are a lot of Shinobi that uses sealing techs.
You can even use a sealing tech to render the enemy immobile... Also known as a barrier justu.
Transport destructive jutsus like bijuudama or even bijuus themselves.
You can even store a jutsu, for example... When Jiraya stored amaterasu in a seal and I bet you can use it against an enemy later.
Curse seals are also powerful, like what Danzo did to Sasuke...
That's just a few...
