I made the mistake playing iso today, and holy shit his util is horrible. I understand he is an aim centric duelist but even if you have the best aim of anyone ISO would still be a shit agent.
the only duelist with no real entry abilities
reyna - flash + dismiss, can also overheal to take multiple fights
raze - satchels, ult
phoenix - flashes, ult, wall to take space
jett - her entire kit
yoru - tps, ult, flashes
neon - entire kit
like what does iso have, a moving wall thats smaller than harbor's lmao
