SE concern about HP Inflation doesn't make sense with existing tank gear

[Brannigan]

I'm not even entirely sure what the hell they mean by "HP inflation"...

You mean our HP goes up with levels/better gear like every other relevant stat to a given job in the game? Say it isn't so.

I don't know if this is how it was in 2.x since I haven't looked at the gear, but in 3.x the VIT:STR ratio on gear increased as ilvl increased. Basically, we gained more HP relative to the strength we were getting as we went from ilvl 180 to 240. With VIT as an attack power stat, if they wanted to lower that ratio then tank AP scaling would get messed up.
