Question about Soraka's items: Ancient Coin vs. Spellthief's Edge
I'm really new to this and honestly have no idea where to post this, so if this is the wrong place, just redirect me and I'll take it down. Or take it down yourself if you're a mod. Whatever works.
I'm new to League (and RTS as a whole), and have been really enjoying playing as Soraka. I read up on a couple of guides, and those plus the recommended items list the Ancient Coin series, all the way up to Talisman of Ascension, as important to start with and build up. A much more experienced friend than I (the one who got me into the game) told me to avoid Ancient Coin entirely and instead use the Spellthief's Edge series and build towards Frost Queen's Claim, focusing on more powerful items later to build her Health Regen. Looking back at the wiki for each item and popular builds (at least according to MOBAFire, which is where Google pointed me), they both look like they could be effective.
Specifically, what are the pros and cons of the Ancient Coin series vs. the Spellthief's Edge series for Soraka? Which should I use when? I can see myself being more inclined to Ancient Coin because I've had way more problems with running out of health than mana for her E. On the other hand, Spellthief's Edge can generate more maximum gold as well as extra AP. Which situations can each be used for that the other can't?

since you don't have many mana issues, just for the active effect.
