I don't have a problem with people who solo because they like to solo. My problem is when certain soloists expect to be able to do everything that a full party can do. Example: In FFXI, for the longest time, you needed a good solid group to take on any endgame bosses. Later, certain jobs/job combinations, with the right gear and macros, could solo most of them. This is fine for me because not every job can do it and you have to be exceptionally skilled and knowledgeable to do so. Now, we fast forward to FFXIV and a lot of soloists are wanting to be able to solo EVERYTHING on ANY JOB. This is unacceptable. If everything is soloable, what is the point of having a party? At the same time, I understand the soloist point of view. Not everyone wants to get a party together and go fight things, but please understand that this game isn't (or shouldn't be) a solo game. Yes, it is solo friendly and will have solo content, but the game isn't going to be 100% soloable (At least not if they want to keep a solid player base) and people need to understand that. There are going to be things that you, as a soloist, will not be able to do without a party and it's the people that complain about not being able to solo everything, in an already EZ2Play game, that really tick me off.

tl;dr I understand the solo view, but not everything is going to be solo onry so people need to suck it up and accept the fact that a party will be needed at some point.
