This is just from my own personal experience, playing RA with all types of melee/ranged and caster professions, monking or rit healer.
I thought monk would be the easiest profession to farm glads, as then at least your team always has a monk, something which a lot of people will tell is required for success. It doesn't always work that way, sometimes you'll face no monk teams with massive damage and your team can't handle it, or the other team has a monk and better players.
No matter which profession I try, I always get longer runs and more 25 win streaks on my ritualist, bringing 5 damage skills a rez and two help-your-team-mates skills. If you don't get a monk at least you have 4 damage dealers to push through kills quickly and a BIT of team based aid, and if you do get a monk, you can still be a damage dealer but lend a hand to your monk if they get in trouble or are not very good.
If you can do the same on other professions great, but I find the spread of skill types for a rit can give the best results, for me, from personal experience.
My main character profession is warrior btw, I'm just letting you know what works best for me.
