GAC Matchmaking

The matchmaking for grand arena is horrendous. Constantly I am getting paired up with players almost double my GP. I have dealt with this since Carbonite V and im in Chromium II now.  There needs to be a Re-ranking around every 6 months or so based on GP and obtained journey guide characters. This would help newer players that are stuck in Carbonite due to players with multiple Galatic Legends that sign up but wont participate in GAC. At this point I am no longer enjoying GAC beacuse of this. It would be much better if the paired opponents were near each others GP and it would be much more of a challenge for the both of them.  I am constantly having to just get my 10 banners for participation and be done for that round because theres nothing I can do. If matchmaking was fixed it would help so much more with consistency in rankings and just overall player morale.
