[Werewolf13]

I've not played DW online yet but played Sub Command online for about 2 years so I've got some experience in this.

Tactics are different when playing a human than when playing the AI. Most of what has been mentioned above will spoof the AI.

When playing a human though things get dicey. One of the things I would do that worked against inexperienced and sometimes even moderately experienced drivers was recon by torpedoe.

If you get a faint or intermittent sonar track on the waterfall I'd put a torp in the water and just drive it (and making sure not to drive it straight in so as not to get a snapshot in return) to where I thought the enemy was without going active with it. the inexperienced guys very often would panic and go to flank which would allow me to lock 'em up easily. The more experienced guys might just speed up a little but that was often enough to get a solid lock.

The really experienced guys would change course but not speed to firm up their own lock on the torp and more often than not would figure out that the torp was in recon mode. They stayed slow, would change depth, course etc to confuse what they knew was a really weak contact for me.

Point is don't speed up unless you absolutely have to...
