Actually less. Especially since crits can remove traits now. I think it just evens out, kinda easier to repair, but also alot more deadly. (Vorlon ships with AA, what fun, for the enemy).
If the NSA crit effects would be removed, crits would be very hampering, but not a potential death sentence.
I had a Kaliva versus 3 Vree ships supersmall game once. 2 crits: No repair and Speed zero (with NSA) on the Kaliva first turn, finished the game for it. The torpedo saucers were toast anyway, but the raid lvl saucer could sit at the back of the Kaliva happily pumping its weaponry into it. That kind of luck is still possible.
OTOH i once had a -4 speed crit on an Octurion once. What fun for the 2 Hyperions and the Omega at my back. They could overshoot or lose their boresights. So much for my slow whale, could turn on a dime all of the sudden. A turn later the Hyperions were nearly toast.
EDIT: sry forgot to mention that this was under 1e. Now it would take 3 crits to do it. Greg Smith is right.
