So he can't use a general statement to give advice for a specific situation?
He's allowed to do that, but you're extrapolating a shit ton (first death = tower lost = enemy is automatically level 6, etc). Being the first death in a lane does not guarantee a lost tower, so when he says "pick and choose what minions you want to farm and leech exp", you extrapolated to say "leech exp from your 2nd tower?", which wasn't what he was saying at all. Pick and choose minions to farm and leech exp, so that you don't endanger yourself to die or lose HP on your tower.
It's called being zoned and/or melee. If you're a death behind, going for cs can be suicidal or very hard without losing lots of resources. Sorry for not being able to get the perfect 6 when behind.
Ranged top laners aren't all too common, and even when they are played, melee champs have more move speed and general tankiness. Sure, you may have to invest into sustain, but it doesn't mean you HAVE to let yourself die in lane when you're at a disadvantage. Being at a disadvantage does not mean you have lost the lane, and it doesn't necessarily mean that you were put at a disadvantage because of dying either. You can be put at a disadvantage without dying, in which case, playing safer is the right choice anyway.
How can you prime the minion hp without using mana or being in a dangerous range?
What are auto attacks? If you see melee minions at 3/4 HP (so after a tower shot, 1 auto attack won't kill them), just auto attack them once to prime them.
If it is dangerous for you to prime minions when the enemy is pushing your lane hard and spending their auto attacks/spells to push the lane, then you're fucking up somewhere in your lane mechanics.
If you let them push long enough, they'll get your turret.
But they also won't have a huge lead over you. If they aren't killing you, they aren't getting extra kill gold. If you are safe and farming effectively under tower, your enemy isn't getting a CS lead over you. And they are at greater risk to be ganked by pushing so hard. You also have FREE pressure on them to damage them and force them off tower, since they aren't likely to tower dive without a lead unless you've managed to let yourself get to 1/4 HP while they are still over 1/2 HP.
I'm talking about after your first death, given the nature of this thread and what the guy before was talking about.
And the very nature of the topic of "dying in League of Legends" has to do with the quality of decision making by players, which is what I'm talking about: decision-making that either leads to dying in-game or preventing deaths.
Getting defensive early when behind means you've spent whatever gold you've got on defense, while your opponent is free to get offence. I exaggerated, but it'll be harder to farm and be useful in fights later on.
Offense isn't everything. You don't see tanks building offense and being useful that way. Tanks are useful with defensive stats. Bruisers/fighters are useful with a mix of offense/defense.
If your final build has something along the likes of a Sterak's Gage or a Banshee's Veil, then getting Spectre's Cowl or Jaurim's Fist (defensive items) are not going to put you behind. And if you have to decide between Sterak's Gage or a Hydra item, and you've died at least once, buying that early defensive item component does not put you behind, because you're going to be getting it anyway and it helps you to stay alive longer in lane to get even more gold and exp.
