oracle, now play her as ap mid and realise how op she is when built straight ap (also take a lot of blues)
GP10s don't kick in for like 10 minutes. If you're trying to rush a Deathcap, then you might as well just straight out buy it.
If you're new, you need to be trying out all sorts of champions. But if you want ranged, AP mid or AD carry is what you're looking for. This weeks free champion list contains 5 ranged champions.
-Ashe: Easy AD carry. She uses natural slows to keep enemies from running, and her ultimate can help the team from across the map with it's stun+slow.
-Varus: One of the harder AD carries. I can't say much on him, since I don't play him, but he has an outstanding poke that hits people from far away until he is ready to move in for the kill.
-Heimerdinger: An AP mid. His primary weapon of destruction and signature skill is his turrets, which he sets up where he pleases do attack enemies for him. He is very slow, and has little escape in exchange for his great damage output.
-Viktor: Can't say much about him, since I haven't use him once in my life. But he is an AP mid, who has a unique item that can boosts his stats that no other champion can get. He has good CC, and high damage, but be warned his primary attack is glitchy and semi-broken.
-Sona: She is a support (to the AD carry.) Her special ability is she is constantly playing rhythms that buff nearby allies for either a damage buff, increased defense, or a movement speed boost. All of these rhythms can be activated again to switch auras, or heal allies, attack enemies, or boost ally movement speed even more. Her ultimate is very valuable in team fights, as it stuns whoever is in her path. She is an easy support, who is fun to play.
Now I definitely have no better word over you, but I'm going to disagree on this one. The amount of time it would take to level to 6 with WW would be minuscule if you aren't spending the time for ganks. Assuming you're doing nothing but clearing out jungle/invading their jungle/cover top+mid, you could reach level 6 before anything major happens to the game.
