hma design is just wrong in the first place, unless you are very low lvl are increase bp by a lot in one day, around first week of playing, theres almost no chance to win last one, im just getting killed by the zanpakutos and not the partners on the last 3
HMA is only about who has faster T1 AOE dmg partner.. without reia bonus and the hp partners have there it is usually over after 1-2 aoe skills with maybe vanguard still alive.
