ALL alts should be easier to gear via catchup mechanics in general. The problem is there are no catchup mechanics for PvP gearing, meaning you have to put in the same amount of time to gear an alt as you do a main, and you have to spend the same amount of time to gear a character near the middle of a season as you do at the beginning. (Actually it takes MORE time to do)
If they actually had some catchup mechanics then you could gear out alts more easily. Has nothing to do with whether those alts are healers or not.
