I have just started 5-boxing again in Rift. After getting the FTL setup going and a decent click bar process for healing I was able to run Instant adventures and Rift pretty easily. I had a 5 man 50th level set of accounts but my warrior account has been usurped by my nephew. He now pays for it and has joined a guild to begin raiding. While I am fine with this I do not want to use the account in my box as I am generally uncomfortable playing in a guild of strangers while boxing. Therefore I created a new warrior and have her up to 28th. With the release of 1.9 I was able to mentor down and start running instances. I quickly realized I had a terrible healing strategy and it must improve.

Group Composition
Warrior : 28th Pally/Reaver/warlord 28/9/0
Cleric : 50th Purifier/Sentinel/Inquisitor 32/34/0
Mage : 50th Chrolo/Ele/Warlock 51/15/0
Rogues(2) : 50th MM/Ranger/Assassin 51/15/0

Now the builds are decent on the Rogues but I can improve DPS switching them to Ranger but the real challenge was keeping everyone alive. The basic plan was to have the cleric spam heal the tank and rely on the chloro to splash heal the rest. This basically worked but I had several deaths. First my mage died several times due to range attackers. The tank would lock up a set of melee but one range MOB would be outside his taunting range and the Mage splash heals would put her on top of this MOBs aggro list. Now this could be an issue of the tank just not being high enough level to have all the tools he needs, such as Sergeant Orders. Also I need to expand my tool set by adding more healing options to the Mage.

SO here is the question, is it better to have the Chloro tank heal while the cleric handles splash healing? The sentinel has several group heals or other cleric builds includes a melee DPS that does splash heals to the group. What are the healing strat other boxers are using for Rift?
