Wow. I do feel for the OP and the misunderstanding of his post. OP if you look at it from the people complaining at you in the BG's point of view can you not empathize?
I don't see how you can go into a bg with 430 ilvl and expect to carry your weight. So while you are not directly asking for a carry that is pretty much what you are getting.
Many people have pointed out why people have gotten you should PvE to PvP mentality by pointing out why people do it. Personally I would rather do something I dont enjoy for 25% of the time and then spend the other 75% of that time fully enjoying things. But I understand there are players like you who choose to do the grind the long way.
I am not one to bitch at players for low ilvl gear in BG's although low ilvl healers do piss me off something fierce because of how match making works
.
In terms for them changing this prior to WoD what would you suggest? Personally I was pissed off when they broke rare spawn farming. I could get full honor gear in 4 hours with it (and did on 5 toons) but they removed this with the latest patch. Funny enough now that this is gone I see more people complaining about the boosted toons in bg's.
I am happy for the changes they will make in WoD in regards to low level gear scaling up. I also understand that I will have to wait tell WoD for it. I also feel that as soon as this happens some players will complain about other players saying they are doing something wrong. After that someone will come to the forums and make a big post about it.
In the end ignore the people bitching at you and play the game. I mean you are the one paying for your account not them
