But still, beating Savage also gives you the best armor, so raiding would always end up with a more powerful character than not. But by putting every reward into raid, you just ensure than your other content will be meaningless for the raiding community, and have reduced value for the rest of the playerbase...especially since we'd still have this cheap tome weapons...
Besides, if something like the relics would actually be the best weapon right away, it could give confidence to some people to try EX Primals (for best accessories) and Savage raiding (For best armor).
