You all could try the most melee friendly stragedy the official stragedy which is the triangle method, same dps requirements as the American version *ie double wicked*

It works like this, dps grab chirada stack on downburst (big warning when its coming) and share the damage, 1k each person, while tanks grab surpana and gurada, when they disappear swap positions so the adds don't build up their stacks, when chirada dies, the melee just waltz over and destroy surpana, no wicked wheels to worry about for the melee's and as a added bonus tank swaps are done with ease and no main tank can't get instakilled if he doesn't pop a cooldown. Only downside to this strag is it requires more from the healers and a bit more movement from the tanks.

On phase 3, same thing and the tanks just pass the spiny when one gets 2 stacks on.
