Yes, I think they miss something,,, specially when that something travels at warp velocity.

But I say don't touch them ( in terms of damage or range) until other klingon problems are solved/fixed, specially the ones evolving polaron to-hit rates, cloak effiency and general klingon warp- power shortages. I dare say that until warp shortage is fixed, so klingons can have a CLEAR SPEED advantage over most of their opponents im similar hulls, any attempt to make klingons relay in distance is doomed.
I wanted to add something else.: I also think that we are falling in a problem, and that problem is conceptualising klinks at the light of SFB , when in fact SFC III does not obey to the SFB spirit . In SFB , in general terms, klinks and feds shared the same amounts of power ( although feds had more power drainage) , feds had overall better shielding but still Klinks matched them in terms of front arc shields and had a clear superiority in turn rates and heavy weapons damage at distance. In SFCIII klinks have normally inferior shielding and are penalized at distance by the super potential of vollyed proximity q-torps. ( and the huge misses of both polarons and k-photons).
The wins i have under my belt on dynaverse have been at almost blank range, making full use tractors, the extra front hardpoint that my ship normally has and the faster-then-fed reload of heavy weapons. Also from what I know, the Ion cannon, a low range weapon, was substantially improved in the beta patch. So, maybe , and forgive me the boxing analogy, klingons are not the distance fighter that they once were, but rather a jab and move kind of boxer, that dances before their opponent.
Yes, we have weaker shields, and armor, but we can throw more punches at them. That has been my philosophy over dynaverse and, if i balance my wins and losses, it proved more successful than my SFB approach to klinks when dealing with feds ( a pity it doesn't work against borgs)
