@ass128: Try to reset your router. Always helped me in this situation.

I always get a lot of hp items because 1) there are so many skills that do a hell of damage (sniper...). 2) most other items are crap especially +damage (imho) 3) you get other bonuses like mana and armor I never ended with 8000 hp but about 5000 hp is normal when I don't need mana for mass heal or something else. And I always get Citadel upgrades so I don't have the gold for so much hp.
For all people that want players rate Karma: Have a look at Xbox Live. After your first 10 online matches all of your friends and clanmates rated you positive and you have a 5-star ranking. When same people rate you bad your friends will just rate you good again. So get a system that gives Karma automatic. And for flaming or something that can't be detected automatic you need some helper that give bad Karma after a screenshot proofed the bad behaviour. Like it is done at dota-league.com ;)
