rageblade is not going to be both balanced and viable

Rageblade encourge sustained damage and staying in a fight for a long duration. that means you will have to be tanky enough to survive long enough. by building tanky you won't have enough dmg item,that puts u in a dead loop. build defensive= not enough dmg, build dmg=won't survive long enough to do dmg. rageblade literally contradicts itself, the only times when it will be viable is when it's number is brokenly high, else it will ever be useful.
