People in Sunshine aren't 'good' at sector. 'Good' is defined by being knowledgeable in what mobs to hit and how. Ross is 'good' at sector, Meaty is 'good' at sector, 68% of Redtopia is 'good' at sector. If you rank yourself decent, which is worse than good, then you're implying that you can't play as well as people in Sunshine. Which means you're 2 tiers down from what 'good' really is.
That's just my opinion from what information you're giving me. I'm sure you're good at one aspect in sector, but their are million of those in the game.
