Did Cryptic ever claim CoV would have those last ten levels at launch, though? Cause I'm pretty sure Arenanet claimed guesting would be in GW2 at launch or very soon after.
there was a lot of groaning out there especially in the pvp areas, when villians was limited to 40 and heroes had extra ten levels. Even though the level sets were 25 30 and 35 iirc. But those extra ten levels is said to make a big difference not to mention the ancillary pool powers that heros got that villians didnt have. SOme felt COV got shafted from the get go and never regained that momentum and the side switch thing was basically a bullet in the head for COV.
IIRC there was a post that stated that originally there was supposed to be 50 levels for villians but the 40-50 content would take a while longer and cause delays.
By definition, they kept their word in GW2. It was available at launch but just didnt work as planned. Hey they never promised it would be running now and forever. They just said available at launch, which it was. Meaning even if it was shutdown 1 sec after launch, they would have kept their word by definition.
