BoL bugs and can still sometimes allow spells through. It's stupid to call for a nerf to it when it's still bugged this way.
Not all sorcs build for max regen, and those who don't build that way rely on BoL, if they chose that morph, to use as it was likely meant to be used: a few times per active engagement; they can't use it endlessly or to run away. A nerf to BoL would totally screw those builds.
And to the person who posted that other thread, no, you're not the only special snowflake who was using BoL before "everyone else started to." People still use Streak. I have only ever chosen the BoL morph because it fits how I like to play, period.
As others have already mentioned, it's regen issues with magicka and stamina that need to be looked at. There are also legitimate L2P issues going on with people needing to learn how to use block, CC, and dodge roll. There are issues with people refusing to comprehend this isn't a 1v1 game or that they can't always win or that the other person may indeed be more skilled. These deserve more consideration before putting forth an impulsive call to nerf a class skill that is not the actual problem.
Disabling the grass may improve performance.
