Stress is supposed to be about limiting your pilot options... for some ships it just does not do that anymore.
The same can be said about firing arcs (hello turrets), obstacles (hello Dash and soon Seismic Torps), setting dials (hello PtL Boost&Barrel Roll Aces) etc. This game is full of exceptions, ships that break or bend the general rules. Singling Stress out is silly.
IMO people should wait for the meta to settle down a bit before they start running around screaming about Dengaroo. The list is very strong versus many lists that are widely popular right now, but it also has weak matchups (ships with low agility high HP like VCX or Decimator and ships with high number of hits per attack,like Brobots or Scouts).
