Needing Mid/Top Lane Assistance
As things currently stand, I'm having lots of trouble. I keep wavering between Silver IV and Silver V, wanting to get to Gold V. My main champion for use in mid lane: Heimerdinger. Why do I like him? He's a poofy scientist yordle with turrets and lasers. He sits in lane and is comparatively safer from ganks due to his turrets severely punishing anyone that comes in. At least, that's the theory. But at least half the time I lose games because I either get outmaneuvered as the Donger (e.g. the jungler is Zac or ganks from the least-likely-to-be-warded/expected regions of the jungle), their team has too much wave-clear (= my turrets die) or tankiness (haha your turrets are hitting me like a pussy because I have all the HP and MR), or my team gets destroyed in their respective lanes or in scenarios where they decide to teamfight when I'm too far away to come help. My playstyle is to at least remain as a passive solid point that pushes the lane and gets the turrets, then helps out other lanes if needed at that point, while everyone else on my team carries their lanes with the lack of pressure needed toward my end (again, in theory). I also have next to no idea when to start wavering from the build that I use for him (http://www.mobafire.com/league-of-legends/build/s6-14-top-mid-heimerdinger-the-revered-inventor-of-lp-70-469381), in part because the game is already gone by the time I've finished half the core, and in part because when I'm building for one scenario the enemy team already dominates in another (e.g. building Rylai's and Liandry's to deal with the tanks when I should have gone for Void Staff or Morellonomicon).
From my latest experience and from what the pro sites are saying, Heimerdinger seems like a trap champion who will never get me to Gold V with the state of the game as it is. But he's also the only champion I've invested a lot of experience in; I don't want to give up this season to learn anyone else for next year. Nor would I believe myself to be able to perform as well if I did take up another champ for ranked. If I were to replace Heimerdinger, I'd want someone easy to use well in ranked, but also able to claim objectives and/or kill the priority targets without any binary requirements (e.g. Rengar's "get fed or AFK" problem).
Refer to LoLKing (http://www.lolking.net/summoner/na/40287279) or other related sites (e.g http://na.op.gg/summoner/userName=Dakka%20Downpour) for further match details. Would also appreciate general light tips that would improve my chances without having to commit to a training regimen or summoner school schedule; where/when to ward, what items should I be getting in what order for which scenarios, runes/masteries, how severely should I lash out at people in real life for driving me past my anger point, what skin I should go with, etc.
This is mainly about my Heimerdinger use, but I also prefer top lane as my secondary; anyone I should go with in there? Having rough times with Garen; currently tentatively considering Nasus/Tryndamere/Jax because "I can wreck anything if I'm given the farm I need" win conditions.
