Even if you take the argument that Soontir is enough for good representation of the frame on the table, it still doesn't excuse the lack of generics and there's room to have a discussion about that.
Personally I think most Interceptors should go down at least 1 point. Alphas at 33 means six on the table. I haven't done the math to compare it to Tie/In with howlrunner though and I think that would be an interesting comparison.
