Except WAR's bread and butter is Dishing Out Damage
WAR can't cure,haste or/and enhance itself or/and enfeeble/nuke the enemy.
Get back to me when all happen at once for RDM without diminished efficiency and/or eventual MP exhaustion. Even if a RDM focused purely on melee casting only self-buffs, a WAR doesn't have much to fear from RDM unless the WAR is poorly equipped. Nobody's saying a WAR shouldn't do more damage, but put the two side-by-side and the gap will be way too big for a job that was otherwise portrayed as one able to fill in a party's blanks.

But let's throw a question out there. Does BLU offend you? For no MP cost they can also receive 10% DA all the time. Ideally they should be sitting on 10% DA from gear on top of that (Brutal, Atheling, Twilight), maybe another 10% with a +2 Khanda. They can Refresh themselves, Haste themselves, Cure themselves and others, Stun, lob MP efficient 'nukes', Erase-ga, create self-skillchains, AoE Sleep, and then some. They also have better gear, better WS selection, and access other traits aside from DA like DW or Store TP without RDM's sub restrictions. Are you parading around claiming BLU broken? Are you actually inviting one to everything you do, potential procs aside? If not, why the freak out?

Like it or not, BLU's set a standard of hybrid classes that RDM should most closely match. The two are still very much capable of being similar, but different, just as WAR and MNK can be flavors of DD. "But set points!" All that I mentioned earlier? Yeah, that's part of my standard build and I'll be getting more set points to play with come patch. And knowing all that and some of BLU's base design choices, it's not hard to see that the job was perhaps SE's second chance at RDM. However, that is by no means justification for RDM to be swept under the rug and forgotten, or irrationally feared for some poor game design features people opted to exploit.
