beyond using tank accessories, which is a good idea, try using those with crit/det.
SCH, imo, is an easier entry into PVP since you have a built-in back up with your fairy.
at rank 40 i have MND filled instead of VIT for PVP skills. the extra 12 MND is better than 12 VIT
if you have all right side tank gear.

also, i have my points spread across all actions. my rule of thumb is 4 points is not worth
putting into a spot for a skill that only reduces recast by 30 seconds.
for example, the SCH knockback skill. its great and has 3 spots;
extra knockback, increased potency, and reduced recast. i choose extra knockback since that is the main reason
for me to use that skilll, ie. knocking people off a ledge. the extra potency is meh and the 30 seconds just
doesnt come off as appealing.
