Well first of all you should try to work toughness and power over 1800. Crit chance should be about 35-40. You can compensate that with sigils later. Vitality is not a problem. For support staff is great and it also lets you tag many mobs in orr=loads of moldet bags. Greatsword could be your main weapon but you can decide that yourself. Mace would be your best healing weapon but still you should have almost every weapon in you inventory because they are mostly situational.
Usually guardians go 0,0,30,30,10 or 0,5,30,30,5 but this also can be changed if you want more damage or support. Virtues trait line will offer you greater support and longer boon duration so you should invest here as well. 5 in virtues is a MUST. Use monks focus for solo play and AH for group play. Empowering might is great if combined with AH and decent crit chance.
Knights gear is a solid choice for damage, precision and survivability. You can also choose clerics for healing and also mix them up.
Dolyak runes are expensive but give you both vitality, toughness and regeneration. Personally I use knights gear with dolyaks.
Too much healing power is not good tho because your main source of support comes from long duration boons, wards and projectile reflections. Wall of reflection is very useful in fractals. Same with shield of avenger. Also don’t forget your virtues. Those are awesome and if you have 15 in radiance and 5 in virtues and empowering might, you can give your party A LOT of might which is always desired.
I hope this helped a bit. x)
