You haven’t found enough tosses for stoker because there aren’t many really, personally i don’t recommend buying him, he’s still almost never picked in the competitive community despite his recent buff (i don’t know about public since i don’t play it, but i’m sure there’s other dominants there like…proxy, duh).
If you want someone who does a similar but better job than Stoker i suggest Nader if you don’t have her yet.
Molotov can block paths, but there’s usually another path you can take instead and you can almost always long-jump over the flames. Throwing molotovs on armed C4 is usually a waste because it can be cleared with sticky bombs, smoke etc. (You guys might disagree on this, but if you play against a good team, they will most likely use Fletcher as engineer, he will screw your molli up.) In my opinion, the only effective molotov toss is the one on health stations but you can destroy stations with other abilities just as fine. I don’t know much about the damage dealt to generators/EV because I never really see anyone use molotov for that.
Like i said above, Nader is way more viable. Her nades are the best pick for destroying most of the generators in the game, she will keep enemies away with her nades being especially very good in choke points. Her grenades are good at destroying and constantly keeping the enemy away from their heal station.
Unlike Stoker, Nader will be able to use her nades during combat, constantly. So I’d say Stoker’s guns and health are solid, but other abilities will just do better.
Of course there’s plenty useful nade tosses. Fragger nades are mostly used to get those well-timed spawn nades to eliminate (multiple) people as they spawn, as well as pushing towards an area with the help of a frag grenade in order to clear people sitting on health stations etc. Is there other nades/aspects you are curious about?
Edit: Two days ago I’ve seen molotov not gibbing the enemy again, twice in the same game. I don’t think I’ve recorded it but I’m 100% it happened, I hope molotov isn’t bugged again after the last updates…
