It’s only up to five slots, not six.
Besides, On Your Mark is pretty much only good for the fifth fragment slot since its perks can pretty much be circumvented with Marksman’s Dodge for an instant reload.
When you put that aside, only Knock ‘Em Down is an actually good aspect since it improves the supers, and that’s probably the reason why everyone is saying that Hunters have a good solar rework since Solar Hunters already had pretty strong ranged supers.
Take OYM away, and that leaves Gamble which has terrible delay time to reuse it, can’t save solar charges after death and takes away two fragment slots.
[spoiler]
Between the lukewarm introduction to the rework earlier this season and the constant threat of blowing myself up every time I tried to use Solar Fulmination on a scorch build, the idea of them trying to make arc work in a 3.0 has turned me off.
Void was great with its respective artifact mods and is still pretty good even after, but once some of this season’s mods leave Solar will be worse off for it and if Arc doesn’t come out of the park nailing it when it does finally get here, I’m gonna turn my nose on it and go back to my Tether, who would never betray me when I’d need to shut down a charging Striker.[/spoiler]
