The bomber was powerful, but honsetly, not many players use it on a classic server, and it required a bomber AND pilot.
Err, on the server I played on (Big Monkey's Treehouse), the Bomber was used gratuitously. As for the Shrike requiring some skill, yeah, it did. Not much, but a little. Unfortunately, none of the other vehicles required skill. Tanks were commonly used to sit on flags, chaining/running over incoming cappers. Any HOs that tried to destroy it would be promptly dealt with by the tank's mortars. That, or Shrikes on defense would promptly run over the HO. Speaking of which...
Nothings more fun than a vehicle chasing you down only to be forced to crash or lose control with a good shocklance.
Unfortunately, when a Shrike runs you over behind while you chase/cap, there's not much warning. If you play LD, it's not too hard to SL incoming Shrikes. When you are skiing/flying at 300 MPH, it gets a tad bit more difficult.
Also, I take it you were an HPB? On the server I played on, most of the players were LPBs and nobody had over 200 ms ping.
