For the real min/maxers, here's an updated version of the original LagunaD sheet with Effective Health. It's one of few ways to compare tank classes with some actual uniformity. I streamlined it for ease of use and updated class stats for 1.4. I think I have all the stats correct for PT/Sin tanks. If anyone can confirm them, that'd be awesome. Obviously, feel free to report any other issues as well.
The sheet has the standard LagunaD Squish, SigmaSquish and Spikiness metrics, as well as Effective Health calculation to compare endurance stacking somewhat. I also added a roll-by-roll calculation of Total Mitigation (a restatement of Squishiness really).
