Yes, Rajas is definitely more useful for WHM than Tamas... yep.
Back then there were other rings, and I didn't mind making other macros.
That one ring could not match up to two - three others, and I felt like I would place a cap on my job where I could expand it even further with other rings.
Rajas was more of an investment for when I leveled a real melee job, but back then I loved to melee as WHM and still do. Even if I didn't like to I think I would of gone Rajas over Tamas, because other rings could fill the role better than a multitasker that wasn't quite as good.
