I have been working on a well rounded, practical and optimal Moira build for quite some time, and I think I have found it. You will be able to do just about everything like duel enemies, dive the backline and keep your team alive. This is a very detailed and well rounded Moira build that anyone could use and is versatile enough to work in pretty much any scenario. It will provide a core build to follow each round that is most importantly AFFORDIBLE. Every item and power is selected with meticulous synergy. I also provide helpful tips and optional purchases depending on the situation. It focuses equally on dealing damage and healing the team with a good mix of weapon power, ability power, and survivability. You cannot go wrong with this build. This build is best used when playing with your team, but you can still pick off enemies easily.
DISCLAIMER: This build does not recommend multi-ball since I don't believe that it is worth taking over many of her other powers. It may look cool but the additional orbs are only 85% effective, which is very underwhelming for most of the match.

[Cross-Orbal] or [Ethereal Excision] are both good powers to start.
For Items I like to start with these since you get a good mix of AP, WP, and AS. [Frenzy Amplifier] is really good here since Moira is great at picking up elims and will benefit from it quite often.
Choose starting items based on your playstyle and the enemy team. Round 1 can be very important for setting yourself up for success.
