Now now, guys. There is absolutely nothing wrong with targetting any subsystem you want to. On the dynaverse, targetting warp and cloak are the only way to prevent someone from running. Having said this, it should not be a target strictly because of the error... but I doubt it would be. Most romulan players will not cloak. Cloak needs work as it stands. And, to be fair, if he manages to scrap both your warp and your cloak, you just weren't paying enough attention. It is wrong to try to use a bug to your advantage, but its also wrong NOT to disable the cloak simply because of this. I think its fair that he should target whatever he wants. It is, after all, a GAME. I don't really see the tactical advantage to targetting the cloaking device, but that's just me. Maybe its because I play Romulan, and we can't hit if we target other than hull very often. So, in my oppinion, with the exception of borg warp core, subsystem targetting isn't that great, unless you're the federation, who never miss. But that's another string.
