Much of the discussion around game balance seems to center around nerfing or buffing individual heroes, and particularly lagging behind their peers seem to be the slow-mana, AoE attackers. Fast mana, single-target hitters like Magni and Sartana and Joon are able to snipe opponents quickly, while the Quintuses and Horghalls and Justices of the world die before even getting a chance to activate.
One possible solution could be to incrementally lower the overall attack damage of everything in the game, making it harder to one- or two-shot heroes and all but impossible to kill them with just six or seven tiles.
Everyone would live longer (say, 10-20% longer) and average and slower attackers would have a much higher likelihood of actually contributing meaningfully to battles. Fast mana heroes would still hit harder and quicker and may still be dominant, but the effects of other heroes would at least be felt. The game as a whole may be more balanced, with a greater diversity of desirable, viable heroes, and a lot less disappointment on the part of players not able to spend hundreds or thousands of dollars to get the handful of heroes who tower unequivocally over all the rest. The best heroes would likely as not remain the same, but the separation between them and the rest of the legendaries would not be quite so pronounced, and the game as a whole would see a marked increase in strategy.
The game timer may need to be adjusted, since battles would unquestionably run a little longer, and there would remain a few legendaries clearly in need of a bit of buffing (Elkanen, Leonidas, Thorne, etc.), but on the whole this might be a better solution to the problem of hero balancing and diversity overall.
Of course, it’s possible what I’m suggesting wouldn’t help or would be more difficult to implement than I imagine. (I wouldn’t lower the attack “rating” of all heroes; I imagine it’d be easier to simply adjust the damage calculus that we, as players, don’t see.) I am curious though what others think.
