Dragon: You want to Dragon earlier in the game when Baron isn't an option, usually after the jungler ganked mid or bot successfully, or forced mid or bot to b. It's helpful to also have tabs on their jungler but not necessary. Whoever aggros dragon needs to move back to drag him to the opening in his pen, to prevent a smite from behind. Mid to late game, dragon is a secondary objective to Baron, a group of one or two people can do it, and it should be done if you know you can get away with it safely, or as a team of 5. 6 minute respawn timer, gather your whole team to dragon about 5:30 into the timer and you should get it every time.
Baron: The ultimate objective and point of contention late game. Gives too many separate buffs in every area to be ignored. Should be warded at all times. If they have an oracles, you can literally put a ward inside baron that they can't kill (like a squishy hiding under a 6 stack Cho so you can't click on them). You want to stay away from bot lane as much as possible. If it's mid game, and they have someone bot, you have to assess if you can pull off baron or a 4v5 while taking damage from baron. Late game, there's no question, if one of them is farming bot, lead your team to baron. 4v5s shouldn't be too difficult at that stage. If you can pull off Baron fast enough their bot lane will be arriving where you are long after you've finished, if they even care (some ignore it). There is the value of how much damage that the person bot lane can split push, however. Losing an outer tower is acceptable for Baron, an inner tower is situational, and inhib is a no-no, forget baron for now. Baron is also something you want to do if you managed to get one or two kills on them without dying or sustaining heavy damage. If it's late game, you usually want to get the outer tower, inhib tower, and inhib, and then baron. You will usually have time for it all. Respawn time is 7 minutes.
Lane Flow: If you're an aggressive laning champ, you sometimes have to hold back so you don't get ganked. Keeping the creep wave in the middle (last hit only, only use AOE when they do) is usually acceptable, with a ward in the river for good measure (don't put it in the bush, you get more range if you put it farther out in the river). If they're ganking bottom and you're top, feel free to be aggressive and push as hard as you want, it's not like he's going to suddenly teleport top. Just watch out for mid. Same for bottom, but bottom is usually more conservative anyway. If you can get your lane opponent to very low health, basically meaning you're full and you could kill them if they attacked you, also feel free to push to their tower. It's harder for them to last hit and they lose gold, while you can keep up pressure and tower dive at times. I like this approach more than zoning, because it's more reliable and easier to keep up (they can't really take potshots at you like you can at them).
I think I got everything in there. Any more questions feel free to ask. Also, being a leader, not necessarily a carry, can win games for your team. I've had games where they've been winning but made the mistake between going baron/dragon/pushing etc. (lolol it's late game and all are mia, let's do dragon! [lol we just got baron, grats on your net loss of gold, exp, and stats]), and we chose the right option where they didn't, and made a solid comeback.
Enjoy elaborating on common sense
Anyways, I just saw something Interesting. Last game I played morde and got the best score of both themes, but thats not the main point of this post. We had a jungle skarner in our teams, and during 20 of the 21 minutes of the game, he had only a wriggles and mercs. Turns out that he actualy did more total damage then I did, as morde with rylai's and revolver. The graph showed me quite a bit above everyone else and him 2k damage ahead.
Skarner's sustained damage is quite impressive, when you look at it this way. He was jungling too, altough damage from smite also factors in, its still impressive.
You're doing it wrong if someone else does more overall damage than you and is within 20 CS of you
