For Heroic Mode, I've got the following heroes accessible
Wolverine (85) 5/3/5
Storm (77) 5/5/3
Iron Man 35 (50) 5/4/4 (My first char to cap and didn't realize there was a cap otherwise I would've done a 5/5/3)
Spiderman (40) 1/3/1
Modern Black Widow (34) 5/5
Modern Hawkeye (30) 5/5/3
GS Black Widow (28) 2/0/2
Invisible Woman (50) 0/2/1
I usually try to use Wolverine, Storm, and one more as those two are my highest levels 85 and 77, respectively. I usually try to use Spiderman (but sometimes sub in Black Widow) just to abuse the stuns. But the game just drags on (as I must focus on blue to feed the stuns), and if I make a single mistake (or have no other tile matches), I expose Storm and Spidey to lvl 200+ NPC attack tiles. They pretty much die instantly (or alternatively a heal tiles goes off and heals the mobs for almost as much damage as I've done). If I don't focus on stun-cheese, I just die to the endless attack tiles that build up as my dps can't match up to lvl 230 NPC dps and the 1800 team-wide heal tiles.
For me, except for the first two encounters, whose levels are 10 and 50, everything else is lvl 200+ (usually the capped 230).
I can win occasional encounters, but it's just entirely tedious and unfun at this point. I was considering buying ISO/coins, but I just haven't been having fun the past few tournaments and PVE encounters as enemies scale to levels that pretty much make the entire thing tedious. I've got a large amount of my roster locked up for this current event. It just kind of makes me not want to play.
There's just a massive difference between mob and hero levels for me which from what I udnerstand isn't standardized across players? Like the top players in my bracket have around a 3000 rating and their comparable heroes are lower leveled.
At this point, I don't know if I'm just clearly a terrible player, or if the player experience across multiple people is just not standard making a tournament/bracket pointless in my eyes. I feel like it's like having a tournament for having a 100 meter dash, but a random selection of players only have to dash 10 meters and get as much (if not more credit).
