#It was super retarded:
We are removing Clairvoyance, Clarity and Rebirth because they are used to troll and they are the least used spells...
(For real Riot?)
They were niche for sure, they were used to troll? YES, but if someone wants to troll they will do so by any means, removing summs because of it is stupid.
Also they were super useful when used properly.
Clairvoyance could be used to set up global or long range abilities such as
ult,
ult,
ult,
ult or
ult, and many others (
etc).
It could be used to set up ganks, help you to get sight of an stupid bush, see objetives, prevent ganks, prevent a team ambush, track the enemy jungler, etc. Deleting it was stupid.
Clarity could have been reworked into something more viable while keeping it's essence like they did with heal, but no, lets just remove it.
Rebirth was used by feed trolls no doubt, but it was an important strategy summ for champs like
etc, and the speed boost could allow you to actually sacrifice yourself for the sake of the team and return quickly to a team fight if used properly.
