we get access to multiple choices for stuns and interrupts including Skull Bash, Typhoon, Mighty Bash, Disorienting Roar, Glyph of Fae Silence, or Bear Hug. Not all of these are baseline some of them are talents, some are glyphs; all of them have advantages and disadvantages. Bear Hug is just one of them.
you have to look at the tools available to you and accept their benfits and limitations. If the root of bear hug unacceptable to you, then choose Mighty Bash, but as it's a base line ability for Guardians, there is no reason to avoid using it when you don't have to move. and there are many tank situations where you don't have to move.
