Guild Wars 2

Removing and changing existing stats’ mechanics to this extend after a month of release? After people farmed or bought their exotic gears? Without pissing alot of people off?

Not going to happen.

OP has a good point. Whom in their right mind will buy those boosters at level 80?

Straight from the Guild Wars 2 official guide @ page 495:

" This process is called tanking in many games, and it’s still an important concept in Guild Wars 2. The new spin on this is that many professions can tank."

“Change to a healing skill that helps everyone. Find boons that add to the group’s survival or damage output, and make those a top priority in big fights.”

The trinity is still here in Guild Wars 2, just that every professions are able to fill into the dps, tank, or support role.
