really all around and in-depth guide. i only would like to add, that whenever i miss to pick the mana refund talents on level1 and level4, i'm a regular, and very thirsty visitor of the fountains. i obviously do care about aborting Q when the target is full, maybe i just end up with extremely aggressive and optimistic teammates constanly on low hp. maybe feedback loop would be a more popular talent on level 1, if shield sequencer on level 16 would refund both safeguards.
