Don't know if anyone does this but had a think based upon my experiences of RYL and believe theres room for a new way of teaming. I am yet to try it, will tonight with fellow froggies. The plan is:-
1 Tanker ("Defender" - high HP)
1 Puller ("Attacker")
1 Nuker
2 Healers (May need a third!)
When then mob your attacking is half dead etc the puller goes off and gets another.
The main tanker uses taunt of both mobs to keep them on him.
This will enable nuker to use bomb or spray etc
This will speed up kill and no waiting between pulls!
No lazy tankers

The team can increase in size but use common sense!
Will need to be all around similar levels, will need higher level healer and tank!
Once experience you can be almost constantly killing 2 mobs.
Bigger team would equal constent pulling

If this has already been covered then I apologise but my experience of teams thus far this has yet to be done!
I look forward to trying it out tonight!!
