Pantheon's Useless Jumping Skills

I'd like to start this off with stating that this is my own opinion, and i would like to see how you feel about this

To me, Pantheons ult is useless. Its takes time for him to jump then time for him to land. It takes too long for pantheon's ult to complete itself, in the time it takes people can just as easily walk out of the area. in order to use it effectively you either... A. predict where the person will be in the 3.5 seconds it takes for you to land. So if they are in the area after those first 2 seconds then the ring appears telling the enemy that pantheon is coming. once that happens there is another 1.5 seconds for the person to move before he lands. the only way that you will deal any damage is if the enemy is dumb/think he can live when you arrive and they don't leave the area or if your ally keeps them busy as you take your time to fall B. you use your ult to cut off the enemy as they run away from your team. you can use it as a herding tool to lead them where you want to lead them. and another thing, ult scales off AP, and most player will play him tank/AD. They ult also scales damage based on where people are standing when people land practically doubling the damage if they are at the center. But lets be serious, you will rarely be able to get someone to stand in the center of the ult for it to be fully effective. Yes the ult also slows people that are in the area but you will barely get people to be inside the ult for it to even work So to conclude, in my own opinion, Pantheon's ult takes too long to do barely anything. It does minimal damage, unless your lucky enough for someone to stand near the center, and it takes way to long for it to work. This is what i believe, you guys could have a total different opinion and that's great. I would love to hear what you think about this.
