Nerfs and Buffs that are Needed (WARNING: OPINION INCOMING)
I've been playing League for quite some time. Despite the anger and toxicity that runs rampant through the community, the game remains quite fun. However, such fun is easily stemmed by 'OP' champions. While they are not necessarily undefeatable, they have a lot of strengths coupled with the absence of prominent weaknesses. The following is a list of buffs and nerfs I believe in my own opinion developed through my own experience should be acted upon.
Azir -Decrease damage reduction from multiple soldier attacks Azir is quite balanced where he is I believe. The only problem I see currently with him is that the difference in damage from multiple soldiers attacking and the damage from one soldier attacking is not significant enough to discourage enemies from breaching an assorted phalanx of them.
Fizz -Increase cooldowns -Increase mana costs Fizz's combat potential is very good. He can trade and burst quite easily. However, he can often do this without giving much thought to the situation, given pretty low cooldowns and mana costs for the utility and damage of his abilities.
Poppy -Decrease ult duration (or) allow players who she hasn't ulted to cc her (though not damage her) I swear most people underestimate the hidden power within this tiny yordle. Almost as bad as teemo. Almost.
Taric -Increase base mana -Slightly increase bonuses from ult The fashionable gem knight has fallen behind in the current meta due to his lack of consistent damage and being split between engaging and playing passively rather than being focused on one or the other like most other supports. It's truly outrageous.
Cassiopeia -Increase AP ratios significantly I don't think I really need to expand on this.
Lucian -Increase Q mana cost -Slightly decrease base attack speed Lucian's ability to quickly poke people to death in lane while being quite difficult to catch is notorious. The increase in mana cost would mean lucian has to make every Q count, and his decreased attack speed would put emphasis on his lack of continuous damage in a long trade or fight comparable to other adcs.
Nautilus -W's damage buff lasts full duration, regardless of whether shield is destroyed or not A lot of high tier players have been rooting for this idea. I think nautilus is ok where he is, but he's one of my favorite champions, so if people wanna buff him I'm not really gonna argue.
Yasuo -He's fine where he is, don't you dare touch him again.
Veigar -Decrease scaling with enemy AP on R Veigar is famous (or infamous) for his ability to cut an enemy mage's life short using only a DFG and his ultimate.
Leblanc -Decrease the hitbox on her E This nerf is merely to let leblanc keep her damage while still ensuring she remains difficult to learn and play.
Kassadin -Give him his silence back (Idea: Have his Q have a delayed silence, giving a second or two for an enemy to try and do something) Kassadin used to be a favorite of mine (I even jungled with him, and still do) but he can't remain in the assassin category as he is far too easily turned on as he lacks any disabling crowd control to keep his enemy from whipping around and exploding him. (And don't say that would prevent counter play, cause you can just as easily pick up the summoner spell cleanse or mercurial scimitar.)
Talon -Give him his silence back (Perhaps significantly shorter) Basically the same argument with Kassadin.
Vayne -Decrease base AD She basically becomes a powerful adc late into the game regardless of what happened in prior phases. (As long as the player has any idea how to play vayne) The least that can be done is emphasis her early game weakness.
Nocturne -Increase passive damage -Decrease Ult cooldown -Increase AD per level (or) base AD Nocturne cannot fulfill his traditional role of assassin very effectively due to his lack of any real burst. His reliance on his auto attacks and his lack of tankiness built this way makes him easily kited. He usually just becomes an initiating tank after the early phase.
That's really all I have to say about that. (For now) I would like to remind the community this is built off my own experience so please don't pelt me with poro snax, although I am prepared for such an event.
