Having utility isn't a bad thing. Having utility that doesn't matter kind of is, and that's what FB/RB/HST are.
Utility that matters - Leap of Faith, Dispersion, Anti-Magic Zone
Shaman utility that matters - Healing Tide Totem, Earthgrab Totem, Ancestral Guidance, Wind Shear
Utility that doesn't matter - Pathetic HPS from Healing Stream, a taunt that takes 3 GCDs instead of the usual zero, a second and a third single target slow when the first can have 100% uptime.
Nobody else has the sheer volume of "weak utility" that we have. A big part of why it's "weak" is how unwieldy it is to use.
Would this be preferable?
-Frostbrand Weapon renamed Frostbrand, shares cooldown with Unleash Elements, deals damage and snares targets with chill effects on them by 70% for 5 sec. Also increases your run speed with Unleashed Fury.
-Rockbiter Weapon renamed Rockbite, shares CD with Unleash, taunts the target, reducing damage you take from that target by 40% for 5 sec. if talented.
-Healing Stream - When you summon any totem, you also summon a Healing Stream Totem (beta version). This cannot happen more than once every 30 sec.
These would feel like useful abilities because you wouldn't need to spend an abnormal number of GCDs to get their effects. It makes them usable.
