Thank you! Finally some people who make sense with their posts!

Yes, most of the advice (if not all) is terrible advice on the previous three pages (page 1-3). Regen tank before pull? Medica II before pull? Divine Seal Cure II spam? Unnecessary and this will create an unnecessarily large risk of getting yourself killed and thus your entire party. Don't even Regen the tank during large pulls unless he/she tagged every single mob with a shield lob/tomahawk or flash/overpower. Performing any action on the tank while in progress of pulling will divert the attention of untagged mobs towards you, rather than the tank.

That said, if the tank isn't tagging everything while pulling and are prone to dying before they reach the end, it's their own fault: Staggerish movement, no use of CDs if it's an exceptionally long pull (Amdapor Keep), inability to tag everything so you can do anything mid pull if necessary.

Whichever approach you decide to go for once everything is gathered up is up to you.
