^^^ Everything up there is correct. You just need to stay in range for exp, and most supports just sit around in the bush for not only xp but a chance to attack the enemy if they overextend. Buy gold per 10 sec items. Also, you CAN take cs, but only if there is no other priority.
The adc was somewhat of an idiot. You weren't taking his cs, just helping him last hit faster. I dont see anything you did wrong.
And I get gp 10 at the 6th and 7th item purchase.
Okay, so if I keep him shielded as he needs it *in the case of Lulu*, I have my initial ward out, then I am free to get CS gold?
Yeah the adc did not do too well, then the next two games failed. 1 to someone who picked a duplicate role, and another I can't remember right now. I don't dare share my current rank >.>
