Players make their decisions on how they want to play based on many things. Some people like to group for everything. Others like to group for only what's necessary. Others like grouping, but only with a specific group of people. The beauty of online gaming is the freedom to tackle content in whichever way you want.
A developer's role should be to provide content to all the different ways in which players choose to play the game. There's a high demand for solo, so there's plenty of solo content. But there's also a high demand for group, so there is plenty of that too.
I see no issue.
