Warrior hasn't got any love because at one point it was the ONLY good enchant in the game. Runeglaive got made because Magus was trash, Cinderhulk got made because Juggernaut was trash and Sated Devourer was made to make Devourer viable while not being stupidly unhealthy (whether or not that succeeded is a question).
Warrior could do with being more interesting but power-wise it's fine. Bruiser junglers were once the only viable junglers because Warrior was the only good enchant at that point. The other enchants were changed so that they could actually compete with Warrior. Warrior doesn't need love because it was the only of the original enchants that wasn't outright bad.
