I feel like solar in general is lacking in solar weapons. Ik yes there's some good ones and a lot of exotics but I wish there were more legendary options
I agree that we having so many excellent solar exotics might be part of the problem, but to me is more about certain weapon archetypes.
For example solar grenade launchers - there is only one adaptive, but we don't have solar exotic GL on the heavy slot. There are also couple of rapid fire, but they are not that great either.
Or strand scout rifles - two are from limited events (Iron Banner and GG) and one is from raiding. As a reminder strand was released 2 years ago.
Obviously they can't and shouldn't release all at once, but in the case of the solar linear I think I have a point.
