Wisp P should be here soon, does that make Gauss the next prime? I was thinking of using him as one of my mains, do you guys think its worth waiting for it till september-october or to just go for it now?
It depends on if you are able to put reasorces into both or only one. If only one, then wait, if you can use some more resources, you can go for standard Gauss. Priming of Warframe is really minor statwise so it's mostly cosmetic addition. Also In the next patch there will be added Gauss Deluxe skin.
