Problem i had with COX is that your range was very limited,like you could only fly so high up and flying was prity slow plus there was a huge wall all the way round each area so only way to change area is to enter a loading zone, i also hated the mission instances there was way to many of them plus when you 1st make your char anyone who started with same char like bruiser all had same powers till you start to level and you could then choose your next power but was still limited, In DCU everyone is diff even from start like if you made a char with super strenth and flight and freeze another player could have like super strenth and super speed and super screem basicly no 2 players are the same ever from start to the end, also in COX everyone starts with same missions depending on the 4 starting points once you finish the tutorial, plus who wants to be a unique charictor i know i do and in COX your not, and who wants to beable to run up a building and pick vehicles and enimies up and smash them on a diff enimy and i got a feeling pvp will be really awsum, imagine a good hero chaseing a villain player flying at high speed and the one chaseing you thorwing fire balls at you while chaseing you but you manage to dodge them, then you fly low and find a hideing place becouse your not strong enough to fight him or her so the one chaseing you looks and cant find you becouse you like cloak in a dark place so he or she gives up and heads back. there is probebly alot more but i said my 2 pence :).
