Why is CCP so Hell bent on making people work together, be it missions, incursions, SOV etc in this game?

You can play EVE with minimal risk and interaction by avoiding any sort of PVP and being smart about things. It just makes sense if you want to get the job done right that you do it yourself. People already have multiple accounts in order to avoid having to deal with corp thieves and griefers or even having to rely on others to light cynos for you.

Personally I think the majority of the player base would prefer just to do their own thing. Burner missions are being used to force feed interactions that no one really wants to have and are just forcing people to get more accounts (tools for the job) and in turn making people use their hard earned isk to buy more expensive PLEX.

CCP stop trying to tell me I have to play with other people to have fun.

That is poor customer service.

This is a multiplayer game. Even if you don't embrace the multiplayer aspect, other players want to work together for greater rewards. When it's just as easy to make X ISK/hr solo as it is with a group, then group play becomes a burden. This is the current state of mission PVE and CCP is trying to address that.

There's nothing wrong with not liking to play with other people, and there's not even anything wrong with wanting to solo an MMO like EVE. Just don't expect to have all the same opportunities as the group players do.

What on earth is a burner mission?

EvE is a PvP game.

Getting out there in your ship fighting other people's ships (one of the ways to PvP in EvE) is considered practice/experience. Under normal circumstances, a person gets better the more they practice (the more experience they gain).

Person A practices the entire time they are online. Let's say 3 hours a night. They spend the entire time practicing because they just buy plex and sell it in game for the isk they need to afford practicing.
Person B practices only 1 hour a night because the other 2 hours is spent grinding isk to afford practicing.

Someone being able to practice 3 hours a night has an absolute advantage over someone who is only able to practice 1 hour a night.

Therefore person A was able to buy an advantage.

The "because you can do it without paying, it just takes longer" is a complete strawman and does not invalidate the P2W concept. In fact, it's because of such a statement that it becomes P2W. If it took the same amount of time regardless if you pay or do it in game, then it would not be P2W as there wouldn't be any advantage to doing it one way over the other. So if person A had to sit in station for 2 hours in order to turn that plex into isk, and if person B could earn the same amount of isk in two hours as person A does by selling the plex, then it would not be a P2W situation as neither one gets an advantage.

That's the whole point behind plex though. The fact you can sell it for isk in a fraction of the time it would take you to go out and earn that isk in game. If this advantage didn't exist, then there wouldn't be any point to even sell plex in the first place.
