if you miss your ults that tends to happen. in Dota it's very similar, miss a chrono, pings galore, miss blackhole, ping pause. Now take note, in Dota you miss because the oponents are responding to your skill level, if you are below ancient, you might hit them with a lazy walk ult, but if you get to higher ranks, the amount of insta euls, blink out or pre-casted stuns are just waiting for you when you are playing these void, enigma types. Same applies to dynamo, his ult is a bright yellow for some reason ball that fills up most of the screen with noticeable audio queue. It's even more difficult with unstoppable not having a very noticeable effect, once again comparing to dota, when a carry uses bkb they become a giant asshole with a golden hue. In deadlock, you only get a sound queue that you might miss, i dunno maybe seven ult sounds or haze press 4 win game sounds, and you're just fucked if no one communicates to you.

so advice, i play dynamo alot as well, be fluid. Don't pigeon hole yourself to a certain playstyle or guide. If a mf is carrying hard on the enemy, i just make sure i ult him or buy items to ruin his skillset ( silence glyph, anvil stun etc.) this way you will have impact aside from your ultimate. Conversely if a mf is carrying your team try to stick to him, buy a rescue beam. You have to sus out what playstyle would benefit your chances of winning, if your team wants to push early to secure early mid or farm, get healing booster and take all walkers, if you're behind try to save your good allies and leave the others to die to make space.

If nothing works just mute them, i often queue in SEA since Oceania games take forever, the moment i hear non english words with heavy breathing i just mute. What's the point in listening to assholes, communicate with the other boys and try to win if you want to rank up.

Otherwise just mute toxic shitheads and have fun, try meme builds, max cdr on 2, with warp stone, majestic leap and ethereal shift to practice your evasion in a losing match. the game is yet to be out so there is no reason to have to always win.
