For those fledgling Paragons out there. Heres a build I've been using and it has gotten me 3 gladiator points so far.
Echo Bard Singer (Yea I played a Bard in EQ)
Ballad of Restoration
Anthem of Flames
Signet of Synergy
Finale of Restoration
Strangely enough, I don't really care for the elites they have given us to use so this build actually dose not have one.
Start off with buffing everyone with Burning Refrain and Mending Refrain. Use Anthem of flame and Ballad of Restoration to keep refreshing them until your fight. Put Finale Restoration on the soft targets.
During the fighting keep refreshing your chants, they will keep your echo's up indefinitely. If someone is being targeted put Finale on them and use your Signet on them. "Watch Yourself!", should be recharging quickly if you are attacking also.
Basically you should be continuously healing your allies, providing protection from attacks and causing continuous burning damage to enemies. Hopefully with Nightfall release we will see other good echos.
