Hey Ken,
Firstly, loving the thread, been reading it passively for a few weeks now, and finally have something I could use help with.
I bought Fiora at release, loving the concept of her, and have been playing her almost 100% of games since, but just can't seem to do well with her. I am an average(ish) player, my CS isn't great, I'm normally only half of what pros get by 10min and 20min marks, and I know that that impacts all champs, particularly carries like Fiora, and I am working on learning to last hit. I try ward when I can, without affecting my core build (usually go for cloth and 5 start, build into boots - aim for AS boots, but sometimes merc or tabi, go for BT, zeal (into phantom later), and IE to try and round out damage). I find it to be good damage-wise, but always end up focused and dead at start of fight.
Have any of you high ELO players had success with Fiora? How do you build her? Are there any tips/tricks you have to offer? Or is there simply no place for squishy melee carrys in LoL?
