The most recent of re-balancing techniques they attempted resulted in this:
They changed something to do with stationary enemies that meant ALL stationary bosses were effected by something and they acted in unusual ways they shouldn’t have been. Random one shots to the dps/healer.
You have to be careful what you touch and be careful also what you wish for.
The healer tank issue we have been discussing recently is easily solved and requires no intervention as such from Funcom. Sustain tanking can stay as far as i’m concerned. They may want to look at some elements of the build as it is indeed a tad OP but it is easily countered by more people promoting the use of traditional tanking methods and the use of the very much needed and required healer role.
