Honestly, CO is leaps and bounds better than CoH graphically and combatwise. More and better costumes too. And you can hybridize more than 2 meager sets.
Except there is one MASSIVE problem which in the end makes CoH immensely better: CO was abandoned. It was.
We've had 1 new powerset and just a few new powers in the old sets, 4 or so sweeping changes to power sets for QoL and updated looks, and ZERO expansions. We were promised numerous things and NONE were implemented in regards to being able to be grey heroes or villains and an expansion. The level cap is the same as it was 11 years ago. And I assure you, your data is correct. I log in from time to time and you're lucky if there is 200 people on at once and you can see the amount of players by looking at the maps and servers. It's sickeningly sad. What a waste of potential.
First, they focused on vehicles and that was all they did for like 2 years. Then they did nothing. NOTHING. Now they have the predatory lock boxes.
Secondly, and to top it aaaaall off; theyve now gotten rid of subscriptions completely. Once a credit card you have in the game expires, you can never re sub again. No one new can sub either. And if you have 24 characters like me, guess what? You have to spend about 300 dollars to upgrade them all from silver to gold so youre not stuck with just one powerset. Hybridization is a HUGE part of champs online. It makes me fking sick thinking about the waste of a game CO is. My card expires in 2021. When that happens, I will never play CO again. Very sad. But Cryptic and perfect world are pathetic.
