I think the game has enough to do so you don't have to raid; which is what a lot of MMOs claim, but all fail to deliver and it devolve into dungeon grind.
I think raids are meant for more stablished guilds or group of friends. To just get them loot, doing the cosmic terminals it's fine.
Most of the content of the game can be done in short bursts, like a traditional ARPG. But if someone has 9 friends and 3 hours to spare; I say give them raids. Lack of gear in MMOs usually lock you out of content and prevent you from playing with friends. It doesn't seem to be the case here. I'll worry if it starts to become the case.
