Magplar healers normally use supportsets instead of pure regen sets. So if you want to make your group more tankier, why not wear wizards riposte, which gives minor maim to your enemies. another possibility would be transmutation, which buffs the crit ressistance of your friends. both are very good light armor sets for pvp. another choice could be spellpowercure, but that only affects 6 friends maximum, but boosts their damage. if you want to debuff enemies with defile, you can also wear duroks bane. overall i would recommend the first two sets: transmutation and wizards riposte (both sets dont have to be active at all time and can be slotted only on sword and shield)
Additionally i would wear a heavy armor set to make yourself tankier. therefore seducer is surely a good option together with tristatfood. if you rather want ot go for witchmothers potent brew, shacklebreaker is an amazing set.
for monstersets i would go either for trollking (gives your groupmembers high healthrecovery equal some healing) or earthgore for the case, real *** happens to your group.
in conclusion i would recommend a setup like this:
heavy earthgore helm
heavy earthgore shoulder
heavy shacklebreaker cuirass
heavy shacklebreaker legs
heavy shacklebreaker shoes
medium shacklebreaker gloves
light transmutation belt
2 rings and necklace of transmutation
1 transmutation shield together with a shacklebreaker sword
1 shacklebreaker healstaff
with this setup, shacklebreaker can just be replaced be seducer, earthgore with trollking and transmutation can be replaced with either wizards riposte or spellpowercure. just switch out the specific armor piece.
I always go 5 heavy 2 light. No point being a healer if you get two banged in light. Even with harness and such, you spend so much time keeping yourself alive, healing others is problematic.
I always go resto and s&b as well so if you get super focused you switch to s&b and turtle up. Having a burst heal on Thai bar if beneficial.
As far as gear, heavy seducer is amazing. You get the survivability from heavy and help with sustain. I then pair it with wizards mostly. Like I said, good players/groups will focus you first so wizards on back bar (5th piece on shield) can really help not only, but the whole group.
You then have room for a monster set. Eathgore is great, but trolls king is good if you don't have that. You can even go 1/1 to buff whatever stats you are missing out on.
You'll want inner light on your main healing bar though to make up for losing crit in heavy.
