Most useless summoner ability?

Oh man i hate exaust after it got nerfed, 70% miss chance? 70% bullshit thats all.
Other than that i the only other ones i dont like would be revive, yeh...

But hey clairvoyance is still usefull on 3v3. Say your playing Ezreal or Ashe or some other Skill shotter who's Ult goes the whole map its very effective to finish them off, correct me if im wrong?

Granted the blind part of Exhaust has been "nerfed", but it now lowers ability damage. A very good swap in my opinion.

Promote? What do you mean?

I only ever used Exaust for getting away. (or engaging with Katrina) but still just lowering
damage over 100% miss chance :/ i dont see how you could like that better.

Wasn't promote casted on minions to buff them? I wasn't around in those days, but I remember reading something about it.

Revives not that bad, its used for european jungling for the champion eve.

Add meh and we can pleh some time

I wouldn't totally agree on this since Fortify can be used for the following:

Say you have low hp and solo lane, hugging turret, there's still 2 enemies who´s gonna turretdive and slay you.. (Or if the turret has low hp they might try to destroy that)
Alright, now is the time you need to pop Fortify, this will give turret 100% Atk speed I think, and it will kill them fast in lvl 1-10 atleast, and if you have Heal + Fortify, you just use Heal when they start diving, and then they r screwed ^^ - Fortify is a good tank summoner spell

Fortify is so short it doesn't do much, it may protect from a couple hits, but if there's more then 4 minions, and depending on summoner/game phase, they can easily dive if you're low hp.

smite ignite heal revive and the tower one. all useless late game
forgot to explain.
ok well high skill level players vsing other high skill level players ussually take a while resulting in late game.

when ur trashing noobs then clairvoyance is useless and everything else is ok
