I prefer to run in groups, so here's my raiding build. It's probably different than most, but I don't die enough to warrant a change.
Health for Power 2
Damage for Power 2
Critical Protection 1
Physical Mitigation 1
Tactical Mitigation 1
There is a theory behind this:
1) Power management is the least of a Weaver's worry, so I can afford to sacrifice power in favor of health and damage. I don't slot the tier 1 versions, as they give less for the same sacrifice. I don't go for the other XforX2 corruptions either, since I'd have a loss in a key stat (damage or health).
2) Diminishing returns take effect when you stack any one corruption, so I opt for a 'buffet' style build, rather than a BK 'stacker' type. Therefore, I believe I gain more in the long run.
3) In any given raid fight, one is expected to get healed. On that dependence, I opt for quality of morale over quantity. I'd get healed for the same amount if I had no mit/prot corruptions, but I'd take hits more effectively throughout the entirety of the battle when using those corruptions.
*I don't P2W, so my class slots don't include the high ranked traits. On that note, I use the fellowship-wide power heal trait for group support. Best to be placed in a full group, and when done so, I've brought up the power levels of the entire group up everytime I can. Good for prolonged fights, and is critical when bringing up the power level of members that are running on empty.
