I know that OP is not serious with this thread but still I have to say that I did enjoy the game a lot more in the past when I didn't play aggressively.
When I changed my playstyle to get better at this game I lost touch of my old RPG playstyle. In the past I only bought RPG/Strategy games (D&D, Age of Empires, Dragon Age etc.) but after a year of playing ME3 MP I only bought games like CoD, Battlefield, Borderlands etc. Being introduced to online multiplayer through Mass Effect 3 gave me the same strive to compete against myself and to be the best I could be much like when I used to play soccer.
Before I started playing online shooters (PvE and PvP) I played video games maybe about 1-2 hours per week. Since ME3 came out I've been spending more than 2000 hours at it (including time spent in lobbies and such), and I've probably put at least 1500 hours on other games during this period of time as well. Then you can also include all the hours spent on forums on the Internet and it just becomes even more ridiculous.
Point is, a cautious and RPG based playstyle made it fun and relaxing while an aggressive playstyle brought out the competitive mode in me and got me hooked in a bad way. Kinda wish that I never started playing the multiplayer part and actually did something useful with my time instead. And from what I can tell, most of the BSN regulars seem to have the same addiction and would probably be better off if they put their controllers away.
