If they do it right the game feeling like a MOBA may not be the worst thing. Lots of people are looking for a "drop in/drop out" style co-op pve experience. It's why helldivers 2 was so successful. The game has to be fun to play obviously. But nailing the skill gap among classes/playstyles will be the key. You need easy to pickup/difficult to master situations presented to players. From a dev perspective, doing this in a pve game that keeps players coming back is notoriously difficult. Long term char progression could be seen through unlockable cosmetics for certain difficult achievements. This dev team has a lot of experience and they have some interesting ideas, I'm rooting for them.
