one of the RC prots is optional and can be replaced by a similar build such as a bonder, or can be replaced by a degen/blood necro which will help with offense
The idea is to cast crystal wave followed by obsidian flame ... this will unfortunately cause exhaustion but by having so many healable chars (either life leech necro or monks) it will be very hard for the other team to kill us between spikes ... we have to call a target, run up to it and smack it hard with a synced crystal wave followed by obsidian flam - make sure you dont lose any more than 20 points of energy due to exhaustion though, if you get close to that, make sure to call it and we have to go on the defensive ... in case you didnt notice teinais crystals and crystal wave are the same spell, you only need one or the other it doesnt matter which.
Another option for the 4th is an ele that has things like heal party.
These builds can obviously be tweaked but based on what I looked up the skill sets I posted seem to be best bet.
