Final Fusedown UptimeM3 - AAC
Relative to the North solo long bomb, Group 1 spreads West, Group 2 spreads East.

Roles can be swapped (T/H short, DPS long).

Scaling of aoes in this raidplan might not be accurate, but I promise you there is plenty of space if melee/tanks are conscious of spacing while keeping uptime.

Tank can move the boss slightly into the 3 bomb safe area to make stacking and uptime easier.

Microadjustments when the aoes appear are possible.
