what makes a map favor fade over sova or sova over fade
how well the recon/haunt work and same for the dog + depends on the other agents you use (jett VS Yoru for example)
i've always thought of it as:
what duelists have good synergy
post plant ability (why sova tends to be really strong on haven and etc)
range needed for util (fade is much better in congested maps)
fade: sunset, lotus, split, bind
sova: ascent, haven, fracture, breeze, abyss
other maps like corrode, pearl, etc are interchangable and depends on compositions
depends on how open the map is. For example, icebox is really open so Sova is much better. Split is not open at all so Fade is better. When it’s a 50/50, Sova is ALWAYS better
some maps are very open and having a drone with visual info is way more reliable than a prowler
some maps are smaller and having a prowler is enough, taking advantage by the fact fade has two
spot has its own situational advantages too; eye is "instant" but has less coverage since it needs a ground, while dart takes longer but covers more and its easier to blend
