Venture has 16m of primary fire range. She also has a more consistent form of self-sustain with the shield after using an ability thing. They are incomparable.
In what world is 16m “poke”? She has to be put in VERY vulnerable positions to do any damage with the exception of finding that right spot on the high ground that isn’t reliable as there’s only a good handful of those and that’s usually just for pressure sake. Reaper and Venture are two side of the same coin. They rely on flanking in, (Dig and TP), doing high bursts of damage with their primary while their sustain being a way to fill their bars (Lifesteal and shields) and having a way to escape that’s elevation agnostic (Drill and teleport). Mei would fall in there in terms of brawly DPS but she has icicles.
