While I agree with this basic sentiment, different games are designed with different levels of craft and insight, I don't think abusing existing rules to unbalance the game is a positive when measuring player skill. When faced with a game that does not fill his needs, a skilled player either adjusts to the game as it is or, if the entire group finds this a problem, goes looking for another game (which can be a modified version of the current game).
It all depends on what you're looking for. If this is a problem for you, I'd say you value the in-game challenges highly. A perfectly valid choice.
This is pretty similar to the point of the original discussion which triggered this thread, except that asking me (who do not perceive caster imbalance as a problem) to fix it was sort of pointless.
No. It goes beyond that.
There are cases where people are clearly abusing the game to break it. Anyone who uses the linked 50 point advantage in GURPS is clearly trying it on. No one ever expects to be able to play Pun-Pun or other such builds. Those are clearly abusive - and the game with them isn't to use them in play, it's to come up with them.
The problem comes in when people aren't deliberately abusing the rules. When a 3.5 bear-themed druid becomes an aggressively hegmonizing bear swarm just because they like bears so they wild shape into a bear, have a bear companion, and summon bears - barely leaving anything for the fighter to do. When a 3.5 wizard wants to stay alive so they buy a ring binder's worth of scrolls because that's what a smart character would do. When they like shutting down enemies so they can't hit back, and start pulling out Save or Suck spells based on the monster's defences while using conjurations because they know that "magic immune" creatures aren't immune to falling anvils.
The problem is when if you make sensible in-character choices you get accused of abusing rules. When because the game designers half-assed the job players get blamed for playing characters that are acceping the rules of the universe, behaving within them, and trying to stay alive - and this ruins peoples' fun.
