Bonus points change in PVP and for tanks. Warrior for example can benefit from both STR and VIT, although most WARs these days who I know manage cooldowns effectively in endgame go full 30 STR whereas others who'd rather play it safe go for a hybrid or even full 30 VIT.

In PVP, many healers go hybrid VIT and MND or full VIT since MND doesn't matter as much.

Also, for those who push endgame beyond its limits such as trying to complete endgame content in the worst possible gear to complete it, changes might also be made to the bonus points.
