Everyone in this thread acts like the only tanks they ever see are so undergeared and unskilled that they are burning everything they have regularly which I just don't believe. If you are saying this is all you see then I assume you are very undergeared/unskilled yourself or just a liar.

Bad tanks exist but I would place them at something less than 50% of overall tanks. Are they all amazing and require no babysitting? Of course not. But are they crap because you had to case Cure 2 a few times in a row? No.
