Gap closers are fun and help me when I'm pulling multiple packs so I can stay ahead of the party. I don't particularly mind Delirium and TBN is one of my favourite mitigation tools for tankbusters because it then lets me deal free damage. I wish PLD had something similar instead of a useless ability like cover. If anything tanking has improved by being simplified for each expansion because I do not miss the days of tank stance dancing and running out of tp/mana during aoe pulls, or worse the infamous "Flash" ability PLD used to have. There isn't anything wrong with tanks being individualized, but if one has a good ability then I don't see why the others can't have something similar.
