IMO, it will be quite hard to clear without the debuff. The debuff lowers the evasion of all enemies in the boss node along with taking increased damage from all attacks. Moreover, debuffing gives you the liberty to have OASW setup in the second fleet for a safer passage through node M without endangering the chance of clearing (you'll be able to kill the entire fleet in day battle 90% of the time from my experience).
