So you started with low gear and now you also complain about people with low gear ? Facepalm.
Go fos - pos - toc5 - wintergrasp - voa and in 2 days you reach 5k or more if you are lucky as opposed to getting lvl 78 gear (nice joke) and running around in bgs yelling "look at me, i haz pvp gear, such rezil, much resist, very stronk, can't touch me" and "i pew pew, you die die".
To reach 5k via bgs it takes you at least 1 week, maybe 2 especially if your team is made up of under 4k gs people wanting to be carried.
"Warmane create a filter like the one for the heroic dungeons"... now that you passed your low gear level era you have the guts to complain about other people doing what you did ? You are ........................ . I'll leave this space for you to fill.
"for at least 200 resilience"... and what exactly will you do with that resil ? Also, there are some classes that benefit from pve items like rogues. Should they be forced to get pvp gear just to fill the resil requirement ? Also, what gs do you reach if you make lvl 78 items ? You reach your 200 resil, but how usefull are you in reality ? One hit and you are dead and i'll just /rofl spam your lvl 78 gear and 3k gs corpse.
I do agree that there should be a system that separates lowbies from geared people but since you said that you started as a lowbie, you can't complain now about other people. Yes, bgs should be from 1k -> 4.9k and 5k -> 6+ or something like that.
But as i said, you as a former lowbie are not in the position to cry about other lowbies. Go farm some dungeons, reach 5k and THEN you have the right to complain about gearless people. At least like that, you show a little respect for your team, you show that you bothered to get some gear.
I first joined my bg with my main only after i got to 5.5. Even now, if i make a new character, i first get pve gear then i join bgs for pvp gear.
