Why is no one willing to discuss creating a balanced foundation for tanks rather than putting up with the constant griping and class one-upmanship that comes with trying to balance fundamentally different mechanics against each other while also having to leave room to make changes just so the classes are not flat out awful/boring to play? I guess it's because people aren't really interested in being balanced per se, just as long as their character is "powerful." They aren't willing to risk losing any one single ability their class has in favor of being far more interesting and versatile overall. I saw this pretty clearly with the Warrior changes; even with all the power and more active playstyle gained, people bitched and bitched about every little style lost. There's no point in having a more interesting system in place of something, it's only acceptable if it's in addition to absolutely everything. And so we end up with paladins and shadow knights having all these new spell lines bloating their lists on top of all the things they can't afford to unmem meaning they can barely make use of what they're given even as they ask for more. I guess what it comes down to is that people would rather eat shit every day than put in some effort and maybe end up with a steak.
If you meant why doesn't the game spontaneously reorient itself to give classes certain spells, then I guess I just don't know.
