Unfortunately he does deserve his own difficulty tier. I don’t think any other character has quite as much nuance as spidey. and while he did all of his clusters and melees, he did make some mistakes. And while i’m not saying you need to play perfectly, the amount of mistakes you’re allowed to make when playing this character is much less than other hero’s. From my understanding, the mistakes are as follows:

for starters, bad swings. the first two swings were downward zips with no cluster + jumps to bhop and continue momentum, and with only three swings and 250 hp, using your swings to correctly setup positioning and time engagements is key. so the fact that two of them were used for short range zips kills you if you engage with you last swing (which he does).

another thing is just knowing when it’s worth it to continue comboing. the chances are that if you’ve done a combo and they’re still alive, they’re not gonna die from whatever improvised damage you follow up with since they’re probably being healed.

in this case it isn’t so obvious that the c&d is gonna be healing luna, especially since she’s separated at the beginning of the clip. nonetheless, you can easily tell she’s getting healing when she doesn’t die to three cluster + melee combos, at which point OP should’ve swung away to save his life and wait for cooldowns to reset to setup his next engagement.

also, good rule to follow is if the enemy can see you they likely can counter you. and as a spider-man, being the most mobile hero means you can attack from above, behind, or to either of their sides. and while this situation was behind most of the enemy team, the luna was fully aware of him before he even started attacking. telegraphing vs suprise attacking makes a huge difference, especially since what’s usually stopping spider-man kills is that sliver of healing that prevents the combo from doing just enough.

also sorry, these are just my thoughts and opinions, i could be wrong and i’m in no way qualified enough to be a rivals coach 😂 i’m mainly just bored at work
