7.4m GP vs. 4m GP

I agree with @TTudor that the matchups are way out of line. I am a returning player having quit for a couple of years and returned about 2 months ago. My skill rating when I returned was out of line with all the changes in the game in the last couple of years. When I quit I did fairly well in Grand Arena and I was daily taking first in fleet. Changes in the game made all of that fade away. Anyway, my partner returned and seemed to be enjoying the game again without having to spend exorbitant amounts of cash so I came back too. I started in Chromium 4 but the last several grand arenas have been brutal and I am unable to compete so I have been "demoted" to Bronzium 4 which is not great but supposedly will allow me to have competitive matches? In the last Grand Arena my first matchup was competitive. He had a narrow account, while my is bloated because I played from the beginning of the game before all this mattered. Anyway, I lost to him by points and lost the next one because I couldn't compete at all. So in the last matchup which presumably would be against someone else who lost a couple of times, my opponent had 50 relic toons and GL Sith Eternal Emperor. I have 7 relic toons and no complete relic team. I took Ahnald's advice on who to relic way back when (bad advice!). Anyway, can't say I can have fun against such an uneven matchup. I'd also like to know why someone with 50 relic toons and a GL is in Bronzium 4??? Please explain or fix the crappy "skill rating" system.
