Translating a CS lead into more advantage
So when I asked people when I started playing "How do I get good?" The universal response was "Learn to last hit."
And I've really focused on that. Most ranked games I play I pull ahead a good 30 to 40 cs in the beginning of the laning phase (I usually have 80/90 to their 40/50).
I play mostly top lane, so I play it safe, focus on not feeding or giving up kills, and denying my enemy laner cs. I do not get to concerned about killing them. I usually wind up 1/0/1 or 2/1/1 or something and they are like 0/2/0 or 1/3/0 or something, and I have a pretty good CS lead on them. I take tower, and go to roam for a bit. They counter roam other lanes or try to take my junglers farm/life, and then when we get to teamfights, I have a few more assists than I did laning phase. but they have 5+ kills and one or two deaths now. They're still barely able to fight me, but I guess they did all right enough to fight my other teammates alone.
What do I do in these sorts of scenarios? If I focus too much on denying farm I end up pulling a ton of jungler pressure and risk giving up kills, or end up missing farm myself. I'm not very good at denying farm outright, but I'm pretty good at zoning (I also play a lot of leona support). If I get too thirsty for blood and run in for kills and dive I usually end up dying and killing them, but no one is better off from where we started.
I like to play champions like renekton, garen, shyvana, nasus, and maokai top lane. The opponents I mostly refer to are snowbally champs like Riven, Darius, and Wukong. I figure starving them early is the best way to deal with them, but am I wrong about this?
Babysitting my enemy laner feels silly, as I'd rather focus on, say, TP'ing bot and taking down the fed enemy adc or something. But then if I leave them alone they get a double kill on my midlaner and jungler when they go to gank mid or something.
I don't want to be that guy who just blames my team for giving up kills to an otherwise starved laner. They're my lane opponent, I should be able to do something about this.
I guess my broader question would be, how do I help carry (not solo carry all by myself) my team from the top lane? Dive enemy carries? Peel for mine? Ensure the enemy top laner doesn't get to do anything all game? Game-by-game basis and I just have to feel it out? I'm really at a loss here.
