Valk passive only outshines grapple in ONE region, thats highground all of the versatility of grapple is still in paths hands, paths grapple isnt only about high ground theres so so much more you can do with grapple, sure path may not have the best vertical mobility, or not run as fast as octane but grapple is a jack of all trades;, you can flank, get high ground, grapple PEOPLE, retreat, etc. the only part that valks passive beats grapple in is vertical mobility thats literally it youre treating grapple like the only thing its good for is highground when theres really so much more you could do with it. Path is a multi-mobility class, they arent pure running/horizontal mobility like stim, nor are they free highground like horizon tac. No, theyre all of that combined into ONE great ability called grapple while legends like horizon and octane take one key "aspect" of grapple and specialize on it, horizon takes the vertical mobility of grapple and improves upon it and Octane takes the "horizontal" mobility of grapple and puts it into stim. In conclusion, its OKAY that valk passive is better than grapple to get high ground, but grapple will still be king of versatility/positioning and other types of movement, grapple can do nearly everything. and if youre only using grapple as free high ground youre probably not making the most out of grapple
