Further nerf to Intimi tank?

[Victor_1]

I know I may be over reacting to intimidate change.
But I'm wondering if this possibly make further nerf to intim tank.

Intimidate

• A successful use of the intimidate skill now sets a player's threat with a monster equal to the highest threat opponent, plus a small buffer based on a player's (size-modified) intimidate skill. Players also gain a +50% threat multiplier to all attacks (melee, ranged, and spells) for a short period after successful intimidation. Intimidate now has a 15 second cooldown, but players will no longer automatically lose the monster's aggro after six seconds.
• When using a shield, intimidate will get a longer lasting and more effective threat multiplier applied

I am curious if we can still maintain aggro from bosses after this change goes live.
I understand if turbine wanted to do something with "be turtle till boss dead" style.
But... well I just hope I'm just worrying too much.
It's already pretty hard to hit certain intim score comparing to DPS character to do its job, at least IMHO.
