I checked out a few things in your profile.
-
support mains at low ELO are hard to carry. While its nice to not take CS, you might want to take a relic shield on tanky supports.
-
I question your itemization choice. It appears that you build the same things over and over without thinking too much into other's build. Looking at your morgana's build where against an Aatrox with heal and warlord bloodlust, yet you don't have a morellonomicon but have a death cap. Theres also 1 game you are as morg against 4 adcs with multimple heals, lifesteal items, warlords bloodlust, and no morellos again. Also your tryd game when building a last whisper against a squishy team with 1 enemy tank that has only 1 armor item.
-
lets have you upgrade to tier 3 runes, and maybe get at least 3 pages of runes. You are aware that you are up against people that have full rune pages?
-
you haven't played a whole lot of games. I don't think you understand the basic kits of most of the champions in game yet. At least play every champ 5-10 times (play them during free rotation), know what they do and what kinds of damages they do.
-
going back to item diversity, I'm not sure if you've tried out all the items yet. try the items in different settings multiple times to get a good feel out of it. make sure you are reading the tooltips properly, and not just glancing over it. (hint: last whisper only reduced bonus armor. so if they've only bought a thornmail, you are only reducing 30 armor from whoever has that thorns, and it doesn't do anything against those squishies that don't have armor).
overall, I wouldn't recommend going into ranked right now. the profile of your account is just not ready (specifically referring to runes here). The people you are teamed with are mostly newer people to match your current level of understanding of the game, so it is no suprise you have "tards" in your game. Its not that they are "tards", they just lack understanding of the game.
I can also see that sometimes you are paired against some higher ranked players. those are likely people doing dynamic queues trying to play some games with the "newer" friends. Those games you'll probably get stomped. But if you do see them, see if you can ask them for advice on how to play better.
for now thats all, I'd go into warding, but I can't see your ward score on my mobile device. But warding is a mechanic you should learn about.
