You are correct.  It has been this way since the game began.  

Ummm... I think he wasn't just trying to point out the obvious. However, you're both correct. In arena, speed usually is king and yet it's power score is so low. I've seen teams with a power rating of 200k have their first turn against a team with a 800k power ranking. I know resist is given a high score but what good is it against someone taking 2 turns and doing AOE damage in the 100's of thousands before you can go? To me, the whole ranking score is completely junk.
