Also, if you notice you're oppent can't defend himself against somthing that makes he has no change to win at all. You better don't use it.
I very much agree. I have characters that can use WoF or balagarn's horn or similar annoying spells. If a person I am fighting is not able to defend against these spells, then I don't use them.
Now, that doesn't mean I won't use them against someone without remove blindness/spell mantle. This means that I won't use them if it 100% disables them and makes them unable to respond. If you, for instance, WoF my strength fighter, you're not gonna hurt him too much. Sure I'll be a little bit easier to hit, but I'm still going to be pounding on you just as much as I would without it. An arcane archer who's hitting on every shot isn't too hurt by a balagarn's horn burst every few rounds, because when they *are* standing up, they're doing close to 100 damage a round (at least mine does).
Basically what I'm saying, like Mel said, game balance can only be enforced by scripting and server rules to a point, the rest relys on the consideration we have for our fellow players.
Now on the other side of that, I will *almost* never complain about someone's tactics. I say if it's in the game, use it against me... but don't complain when I respond in kind.
If I know your character type and refuse to duel you.. well that will rarely if ever happen, but if it does it's only because I know I have little if any defense against you with my current build. Most of the time I'll still duel you anyway.
The *only* issue related to this I really run into... if you're going to cast WoF on me and then silence yourself... well dont' get all pissy and call *ME* cheap when I turn around and remove blindness instead of letting you pound on me... (ok.. so that only happened once).
PvP in Neverwinter nights is very much Rock/Paper/Scissors... No matter how often you win, there's always a build out there that's gonna beat you. And it's quite likely someone you've killed will be able to beat them. Every build has its strengths and weaknesses, and few are universally uber.
Only real thing I can't stand is stealing someone's build. If you can't use your own mind to come up with something unique on your own, don't pvp. Sure there are a lot of mroe obvious builds taht are popular, but when you notice someone's kickin ass out there, don't try to rip off what they've come up with.. that's just really lame.
