From Bronze to wherever

Just checked your recent games (I know I'm not the best of players but just a small bit of advice for you, mainly for ADC).

Firstly your summoner spells. I've noticed you have started to use flash while playing ADC which is good, the most used summoner spell for a reason, extremely useful for getting the kill, or escaping death. But there is still a slight problem, you're running ignite. If you really know what you're doing (Mainly a higher Elo smurf playing in lower elo) then using ignite could work for you, as you are more easily able to outplay your opponent. Instead of ignite you should be using flash/heal combination, using heal allows you to survive longer in a fight, similar to flash it can help you help you survive death, or even in some cases help you get a kill as it gives you health, but also gives you a slight movement speed boost for 1 second. It is the most used combination of summoner spells for ADC, so take that into account and use it.

Secondly, yet again for ADC, your item builds. Saw that in one of your games you built a thorn mail as your 3rd or 4th item. It's an item that should never be built on an ADC (Except for when you're playing Ashe in the tutorial). The only armour/health items you should generally buy is either a guardian angel, or a banshees veil, one of these should be build towards the later stage of the game (someone of higher Elo may want to correct some of the information I'm giving here). As for your item build, for Lucian and Twitch (and a few others such as Vayne) you should buy BOTRK as your first item, Bloodthirster isn't a great first item anymore due to the changes.

Here is a build order graphic which may help you out: http://i.imgur.com/kAodGGp.png

Don't take this as me hating on you, just wanting to give you a bit of advice to improve.
