I feel like that's kind've invalid because you could say that about either grenades. As long as you're in optimal positioning, as in a spot that you can either escape or evade the grenade easily then what you said still applies. And with the wombo combo, if you're going up against adequate players, they'd throw the smoke grenade first to lower your chances of escape. And either situation you'll most likely be killed if they're right next to you to deal follow up damage (just to nullify the grenade/melee op concept).
