[Tanks] Off-tanking Overcap Support

[edewen]

Specifically for paladin but It could apply to other tanks as well.

When tanking, There is overcap protection using Sheltron. The idea is, when not the targets target, to instead of using sheltron for overcap, to use Intervention on the targets target assuming they are

1 a tank
2 not invuln
3 in range
4 not already under the same effect

This could definitely apply to the other tanks offtanking tools as well.
