Guide Shield math: Heavy vs Medium vs Light, is the weight worth it?

The three shields, straight from the DB: Heavy = 80 charge, 52.5% mitigation, 15% move penalty. Medium = 70 charge, 42.5% mitigation, 5% penalty. Light = 40 charge, 40% mitigation, no penalty. The Medium is the sweet spot for most runs - you lose 10% mitigation vs Heavy but only carry a 5% move penalty instead of 15%. Heavy only pays off if you're tanking a boss.

This matches my experience. I run Medium 90% of the time and only swap to Heavy for a Queen or Matriarch fight.

Good breakdown. The 15% move penalty on Heavy gets people killed against anything that flanks - mobility is mitigation too.
