They worked perfectly fine for me, actually even better then the Paveways, so I will definitely be using them when the update goes live.
but tbf I only tried them out in the first Dev server, idk if they changed anything and I haven seen anything being mentioned in the datamines, besides the texture change.
So apparently Gaijin is “buffing” the Su17/Su22’s in the dev server by allowing the use of T and L Kh variants.
Still not gonna make the new premium worth it to buy but is useful to know.
