Towers are a crutch for bad players
Remember this.
If you are under tower you are the bad player, you deserve to be punished and dove.
It seems these boards want towers to 1 shot everyone while they are farming PVE style in their little safe space under tower unable to be touched by the enemy who's trying to win the game instead of last hitting AI controlled creeps thinking he's so good.
Maybe League of Legends just isn't the game for you - you know, a PvP (player vs player) game that requires you to actually fight other players and try get an advantage over them to win?
Too many times I see these bad players just auto-concede lane and watch me while I farm waiting for their minion wave to crash under tower. I assume it's the same guys posting here, those who would avoid any sort of trading as much as possible so they can "not feed" and safely farm under the protection of their caring towers.
Guess what? None of these players have been above gold or low platinum, they never learn anything on how to actually win the game by doing this and they put all their cards into their team, that's not the way this game is meant to be played.
Tower is something that is supposed to help you when you are behind, not something that's supposed to win the game for you.
You're not skilled if you are sitting under tower and farming, not at all, you didn't "control" the wave for it to crash under your tower, you are just not trying to lose that's all.
Lastly, don't give me that "Oh but he counterpicked me" bullshit as an argument, being counterpicked doesn't mean you should auto-concede the lane and then write in all chat how XYZ counters you (some games ago I was playing against a Garen - probably one of you guys crying about towers being too weak and he claimed that Renekton counters Garen, then against a Teemo who swore Renekton also counters him and so on) and that's why you lost.
Unless it's an extreme counterpick situation such as Gangplank vs Pantheon, you have no reason not to expect to win the lane by csing better, trading better and just understanding the match up better. You don't need towers for any of that, they are just a crutch for garbage players to rely on.
Oh you got tower dove by 3 people? Should've read the map better. Tower is not your fountain to beam everyone trying to kill you and save you.
beat almost every single melee champion without a hard gap closer from start to finish with literally no chance for their opponents to fight them. their kits just hard counter champions like
to the point where there is no possible play they could make on their opponent that they can win (were assuming the people who are playing these ranged champions dont make iron 4 levels of mistakes but simply play the lane out normal)
if neither side makes a grave mistake, it would be impossible for these melee champions to lane against these ranged champions.
vs. 
goes, renekton has the advantage. between a good garen and a good renekton, the renekton beats garen off his sustain advantage, higher damage during early levels, superior waveclear, and the ability to dash up to the garen and waiting how he reacts with his w. the garen has to play a guessing game when the renekton autos him with his stun, which makes the play unreliable on garens side. the only way for garen to win a trade vs. renekton is to w parry renektons w. but the pressure to predict it lies with garen.
