I thought revive had potentially good uses rather than troll feeding. I believe Karthus players used it often? I'm not sure what for, maybe to instantly revive and use ult?
I think there should also be multiple new spells because in my opinion, seeing 10
in every single game with the exception of some junglers like Hecarim or people like Singed is really getting old.
Maybe one spell lowers the cooldowns on all other spells for Q/W/E combo reliant champs with more higher cooldowns but the cooldown reduction is based on how large the cooldowns already are so people with already small cooldowns can't go into URF mode every like 5 minutes. Or one is a sort of shield that lets you gain mana based on how much damage the shield does to you for tanky-mana using champions obviously non-tanks wouldn't use that since if they're getting a lot of damage on them they might not be able to even use the spell effectively, but who knows. Another good spell idea could be used for wave clearing for those champs who are more single target based and can't push well, or for those who want to split push like a 45 second cooldown minion wave execute.
I personally think that {{summoner:2}}
are all underrated as well. Clairvoyance can be used for global ult champions very effectively, Clarity can be really effective if you want to spam your abilities and could help win lane easily, Barrier is better if you have larger health and intend to tank, and Cleanse could also be used by tanks in combo of barrier.
There's a ton of possibilities for new spells, revive was cool and should be kept and if not more spells would be so awesome and maybe slight buffs to the current ones that aren't picked often so that people could be encouraged to use it.
