Temporal Divide, while a neat ability, feels not as useful as i hoped.
While the barrier is useful at times to help deter snipers and protect teammates off point, i find the cooldown to be too long and the protection it renders to be a tad lacking against flying and overhead enemies/ults
I do have an idea as to how this could be remedied.
Rather than the barrier be larger over all, have it become an expanding dome shape that starts out roughly the size of Atlas himself.
The barrier would expand for its duration, becoming slightly smaller than Makoa's barrier. This would provide greater point defense for Atlas and teammates against flying/overhead enemies like Drogoz, And Willow.
The new barrier would also potentially counter ults like Imani's dragon and Victor's Orbital Strike better. Maybe even "eat" Skye's ult as it lays on the ground, if caught by the expanding barrier.
I feel the long cooldown would certainly be justified then, maybe increasing the durationby 1 or 2 seconds.
