Omniknight Underused and Overpowered?

My question to all of you is this: Is Omniknight not only underused but at the same time overpowered? He has a 7 second immunity to physical damage which he can use on the entire team as well as a 12 second magic immunity for one person. These two things being said, he also has an aura and a 360 damage/heal! The aura, Degen Aura, give a %28 slow to attack speed and move speed. He is literally the Chuck Norris of supports. His team fight is unmatched, I rest my case.

I'm also wondering why he's not picked more often in competitive matches.

I would love to see an omni in a competitive game. My guess why he is not picked is lanes. Without a stun he might not contribute a lot to a tri lane and he has no escape for a solo lane. It also might need more gold than he is worth, and farm would be better to give on other heros.

I think the main reason would be his ulti could be wasted in competitive games. If the other team has QoP, KotL, Luna, Enigma, Magus that will be a lot of spell damage coming that the angle can not stop. On the note of angle can not stop if naga uses her ulti she can decrease the usefulness of it.

This is all me brainstorming, I really do not know the definite reason.

I disagree that Omniknight would be worthless against a team like Queen of Pain, Keeper of the Light, Luna, Enigma, and Magnus. He would still be able to place repel on his carry as well as his ult. Plus he has a heal/damage spell AND an aura. If he used repel on his carry then Luna ult would do nothing. AND Luna would not be able to auto attack damage our teams hard carry. Regardless of the enemy team outputting lots of damage, they still get partially shut down by Omniknight.

We can obviously agree that no team is going to pick that team constantly. Black King Bar on 4 heroes on repel on 1 hero means that they lose every teamfight. Omniknight has an ult which shuts down heroes like Faceless Void as well. Chrono into Omni ults means it's worthless. Amazing hero right?

But still, Diffusal Blade can counter Omniknight.

I think its more he doesn't fit into the whole team composition. He can't gank well, He has only alittle push ability and can't turtle either. In the tri-lane, he has no stun and needs to get close to be effective.

Satyr purge, Shadow Demon, Doom.

Very useful hero, but he is situational. Laning/early game is a big issue - to get his heal/nuke working as an offensive weapon you need an aggressive + melee lane partner...but 2 melees does leave you open to harass.

He also needs a bit more farm than most supports or he can't make proper use of his abilities - you want to be able to spam heal/nuke for pushing, farming and to keep the team topped up. It's really your only offensive ability, you do very little damage without farm.

He can work very well in pubs where you end up vs 4 carries and killing their DPS = team fight ownage. In pro games he'll struggle to have the mana early game to counter-push with his heal, and lacks lane presence.

I would argue Repel is actually a good escape, it's very hard to chase you down at that point unless you're Weaver, Queen of Pain, etc.

He's not picked in Competitive games because he is a melee support (that reason alone). In this case Warlock would serve a much better purpose than omniknight. Pretty much ranged healers and supports are more needed than the melee supports. In pubs, however, if played properly, omniknight will own the game like it's his personal playtoy.

It has nothing to do with range. Tide is a common support and he is melee.

It's because his animations suck, as well his ultimate is a big warning flag. You just run away once it's popped, or you can get a diffusal and purge it. Also, shadow demon is popular right now and his ultimate can purge it as well. Omni is just an easy to deal with hero, he's good in pubs but that's it.
