I've been doing a ton of research trying to nail down exactly what kind of tanker I want to play. Thanks to my StJ stalker I no longer am looking into damage, I've got that type of character covered. While reasonable damage would be nice on the tanker given its better aoe what I've settled on is trying to make a tanker that is as indestructible as possible. While doing the research I came across a thread comparing SR to invuln on its effective health pools. The discussion made it quite clear, even more than was previously thought that all powers are not the same. Iirc invuln was something approximating 5x as durable. While invuln is likely the best choice for the tanker im setting out to build I'm here to petition those who understand the complex formulary involved with this game:
What is each power's EHP at full health?
What is each power's EHP at its optimal/suboptimal setting? (SR ehp goes up as it loses health at certain resistance levels, WP gets massive regen when surrounded)
What is each power's EHP/sec? (Regen might play the biggest factor in this distinction)
What is each power's worst ehp scenario and what is its ehp at that time? (Invuln when encountering psi is likely to have lower ehp than willpower)
What is the best secondary to compliment primary ehp? (MA might compliment WP better than invuln seeing as it helps shore up def with one of its abilities)
When fully IOd does the EHP meaningfully change versus what it was capable of at just reaching 50 with SOs in relation to the other powersets? (Invuln when IOd can plug that psi hole quite effectively and reduce its primary weakness)
I want to eliminate from the equation any of the special gimmicks a particular power may produce such as damage auras, or self debuffs that dont directly affect tankiness. This post is here for pure survivability, not utility or dps, so yes even stone could be strongly considered in this situation. In broader play these gimmicks wildly change the usefulness of powersets but at what cost/benefit? Knowing a far more accurate survivability can help understand the justification for taking those specific gimmicks over pure survivability. If stone is only just barely tankier than invuln then it can be disregarded in the broader tank conversation but if its leaps and bounds over invuln then it might be worth bearing with the debuffs. In my research I didn't come across any post that singularly could answer these questions so I was hoping that this post may consolidate that information that is spread across the forum. I realize that not everything to do with tankers is just being hard to kill, but it is an important aspect in the tankers relationship with the other ATs. This is a lot to ask but I hope by asking those who are knowledgeable in the game and likely have already made excel spreadsheets about this, we may find something a bit more definitive, or at least updated so it is easier to understand how to leverage the tanker's inherent value.
