I currently have 3 characters that I try and cap Conquest with each week. Each one of them is at least at 1800 rating, and they will all take at least fifteen wins to cap out on points. This is at least 45 wins across all of my characters. I have around an average 60% win/loss ratio when looking at how each character does, so I'm actually going to need to at least 75 games each week to cap out Conquest points through Arena. If I have a 10m queue time + match time (not unrealistic), I'm looking at 12.5 real time hours of WoW just from Arena every week, assuming that I have a positive win/loss ratio, or do not improve my ratings.
I think I speak for many people when I ask for the reason behind this change. Arena is not about gear. In an ideal world, everyone should be working with the same gear. However, this is still a progression based game, and I realized that the way Conquest points were awarded this season was an effective compromise between progression and accessing gear quickly. But now, however, I will need to either devote eight more hours than I'm used to to gain the same amount of gear. On a "fun" level, that just seems wrong. This change will not help balance the game, and serves only to reduce the number of points that people are receiving. Again, I would really appreciate hearing the reasoning behind the change; all I can see is that people in Arena will have to work harder to get the same result, with no other appreciable affect.
I don't want to be the forum poster who just says "This is stupid", but you know what? This change is stupid. It makes my life more difficult, reduces my incentive to play in Arena (which is already not as mainstream as it used to be), and overall reduces the fun I will have by playing this game. A similar change would be halving the number of Valor points gained, but allowing a player to run 10 random pugs. The change would have a similar affect, and would be just as pointless.
