Rdm currently has 3 aoe options. Scatter spam > enhanced moulinet spam > contra sixte on cd. You can even work manafication in there to get even more enhanced moulinet spams if a pack doesn't die quite as fast. The number of options is fine compared to other casters where blm has flare, thunder 4, foul and fire 2 you don't really want to use after you reach level 68 anyway for trash and smn has bane, painflare, shadow flare, death flare or akh morn.
