Many, if not nearly all healers are more than good in brawl, Lucio doesnt stand out much. Deckard definitely stands out as one of the best in brawl and “problematic” in TL (if you survive early mana issues). Stukov is similar.
Personally Im not a big fan of Auriel in brawl, she snowballs a lot both directions. If you start to lose even a bit, Auriel becomes soooo much worse.
