Why normal strategies and compositions don't work in low elo
So first off, I wanna say that playing by the books or meta is not a bad thing at all. But I want to say that it's stupid when people force it in a normal game with a bunch of silver and below ranks aka low elo since most people are probably new or practicing new champs and not really try harding to win.
Several games, I have a much easier time and higher chance of winning where I do weird stuff like 2 top, or 2 mid, or 2 jungle, or 3 bot. I know what you are thinking. You think im a troll and i need to get reported, yes i hear that all the time. But trust me, in low elo, most people have no clue what they are doing.
A lot of people in low elo think there's a jungler because there has to be a jungler, that there needs to be someone farming jungle camps so more gold is spread around to the team overall. But what people don't understand is that, to have a jungler, you have to sacrifice a person who could have been in lane to actually jungle. And so, the reason people ever sacrificed a laner to farm the jungle, was because the jungler will outweigh having another laner in lane to pressure a lane. But what do most people in low elo do? They literally just farm all game.
A lot of junglers in low elo have no idea wtf they are doing and don't put enough pressure on the map to make it worth sacrificing another laner. I'm not saying a jungler needs to be 100 percent perfect, but they need to do more since they have more time to roam than any other lane. They can do a lot more than just power farming. Also, power farming isn't even that good as it was back then with how powerful jungle monsters are and how little exp and gold you get from them compared to older seasons. Sure, some specific champs can power farm well, but not all champs.
So back to my point, I feel sometimes it's more effective especially in low elo to just go 2 top, or 2 mid, or 2 jungle because if you go 2 top, the solo top laner can't farm except under turret, all the while, 2 people can just harrass them for days and take down first tower quick. With that amount of pressure, the enemy jungler has to either camp and basically stay top but have a disadvantage because they have smite instead of ignite and they basically aren't jungling anymore because they have to babysit top so other lanes don't have to worry about getting ganked by the enemy jungler. If the enemy jungler ignores 2 top, usually in low elo, the enemy jungler doesnt even do much, they just farm their camps, base, farm our jungle camps, base. They don't really apply much pressure on the map so 2 top basically wins.
In 2 mid, it's basically like 2 top but better because since the lane is shorter, if the enemy jungler actually does gank, it's easier to escape back to turret since the lane is shorter. And generally the mid laner is squishier so harrassing them is more effective than 2 top.
2 jungler seems very troll as one person will be extremely behind on exp and gold since jungle camps don't split exp anymore, but if you ever seen a double jungle gank, you know that shit is strong. Literally the enemy could flash but still die because when 2 junglers with hard cc and or dash gank, they have so much crowd control and mobility they just get a kill each gank and in low elo, most people don't know how to ward or have no map awareness so they usually die each gank.
3 bot is same, you just pressure the bot laners and take down turrets quicker. Having 3 people means more ward coverage all game from enemy ganks. So if the enemy jungler ignores, then bot loses tower and then the 3 bot can just rotate mid or top and take another tower and/or dragon.
All of this doesnt work in ranked or more high skilled games because most people actually play try hard and know how to play efficiently. But in normals around silver rank and below, generally most people are such garbage at the game that it's just a lot easier to not play by the books. Zed support, fizz adc. Sounds bad in higher skill games, but works well in low elo where people dont know what they are doing or are just practicing. So before you criticize and call people a troll and basically give up, know that it's a normal game and that it's actually more effective. Don't believe me? How often do you see yi, katarina, trynd carry in low elo? Why? Cuz people don't know how to coordinate and focus the threat.
