5 vs 1 Fed science vessel, barely gets damaged. Another engineer ship shows up and heals= game over for Klingons at Captain level.
Taking VM, Subnuc, and even FBP out of the picture, if just one of you had TSS III or TSS II and Tyken's III and Siphon 2 you likely would have dropped his shields all together. Now, if two of you had worked remotely together you absolutely would have dropped his shields and killed him in under 5s. Didn't have TSS ready at that time you say?, no problem, BC and break combat, switch out, come back...profit.
