Yeah they could bring in hardmode flashpoints to possibly bring enhanced gear to non raiding players however they would still miss out on the end game story content like Soa. Ultimately i feel that if they were to bring in 4 man operations it would better bridge the gap between flashpoints and operations thus allowing more people to get into them and actually know what they are doing having some level of experience from the 4 man version leading into 8 or 16 man

True enough however you could stagger the tank fights having to defeat one then the other, and the same again for the pillars. So there are ways to accomplish this

Except for the fact that flashpoints are built to get you gear ready to start operations. Meaning you miss all end game gear, and yes i know you can smash out section x at every available chance but thats a far cry from the story driven content you get in operations

I don't know about the rest of the community but I for one would like to see all operations offer a 4 man option, Raiding is fine but it turns the game into a chore having to log in at a specific time multiple times a weak and being dragged through progression. I know it would take some doing but i believe making a 4 man option would make the game more relaxed and enjoyable and it would also open the game up to a lot of people who have not currently played end game content.
