From most recent patch notes...
Templar
Dawn’s Wrath
Eclipse: This ability and the Unstable core morph can now only be active on one target at a time. This was done to prevent situations where placing the ability on multiple targets would break the ability since there is a cooldown to the ability progressing through each stage.
ZOS tries to radically change Eclipses functionality, introduces an interesting but complicated stage based mechanic which breaks it working on more than one target and instead fixing it or reverting it just decides to cap it at one target; so it now is a much much worse version than what's on live. Multi-target now single target, less damage done to attacker, no heal return for caster. All that traded for a snare/root that will be ignored by 99% of Stam players and a stun that may or may not go off making it unreliable to time with burst.
