As the title says, i've been wondering whether it's more time/ cost efficient to stack lucky picks to help me farm up for larger items before selling them on or to simply go straight for the items in question, component by component.
Then surely this is quite simple you say - simply work out how much money you can get from the lucky picks vs their cost and work things out like that. There is a complication: you are generally more powerful if you go for the item componants -> lucky pick gives you straight ap and not very much of it per gold in comparison to pure ap items like blasting wand. So how significant would the extra kills/last hits you might get be? Obviously by adding this in, I'm destroying any chance anyone has of coming up with a definite answer, unless it's more cost effective to get item componants anyway.
An example of this is my Katarina build, it's pretty standard:
(don't make an issue of this, I find the extra up front survivability allows me to be more agressive if going for a kill and gives me a better chance to get out as well, despite the lower long term prospects for my average hp. Also I can get a health potion which is handy for living longer than I should)
(boring, very standard, will have it pretty sharpish in a two man lane)
Mejai's Soul Stealer
(Again pretty standard, will have this by level 7 or 8 if things go well in my lane, alternatively I can go for 3 lucky picks at this point and get the book at level9-11)
(This is the problem item, I tend to get Rylai's 11-14 can't really be sure whether or not the lucky picks are worwhile getting... They're probably more reliable as an income source than I'd be otherwise however, the componants of Ryali's are pretty good for keeping me alive/killing things)
(From here on I don't have enough lucky picks left for it to matter)
(just here cos I wanted to finish off my build.)
