Trydamere Abusive Playstyles

Trydamere has been popping up in more of my games and I see a trend in the makings of hyper carries where no one will build sustain but full out damage. However there is one class that abuses this to the max and I think its fizz or Trydamere. I've had a few games in which Tryd would carry and he would never ever fight unless he had ult. In team fights this is very painful as every tryd never builds tank however even with 400 ap and about 30% mr I barely did any damage. He had only one damage item and that was infinity edge, the rest was crit, and then out of nowhere he dealt over 600-1000 damage with one hit and even my shields couldn't even help. Things like Kayle, Tarics, and zileans invincibility are balanced. However unless you're able to start the fights then you'll mostly lose. Same way with lane where it wouldn't be a clutch but more of a cheezey move to snowball and even if you are able to snowball his team probably is also winning and if not then your lucky. Same with fizz who only needs one item to snowball a lead which is very painful because his is on a normal skill and everything is horribly overloaded. Can we get some nerfs to them? I think they rely on more of tilt and abusing game mechanics in order to get ahead. Even if tryds ult is only 5 seconds the crit every strike is just way too much especially if he spins to catch up and the team ccs. I don't think even 3 seconds would help I would say 2.5 (Because if timed they could just tp back to base and not suffer any consequence), also the fury part is very annoying to deal with especially with the rune triumph right after. But they usually heal 500 so if they do nerf to 2.5 seconds or so it would make sense. But nerf his damage somehow or someway it is very unfair. Even to other oneshot champs that rely on aa crits or ap burst the deuling potential and team fight engage is way to much. 5 seconds; is a very long time in LoL.
