I agree with that 1000%, I mean just as an example. My gf and I (back at level 80 or maybe it was 82 cap) Duoed Beth Normal first boss, and succeeded on 2nd a few times. By duo I mean two players.... we needed all 6 characters in there, but we worked the strat and made up for the lack of straight dps with debuffing classes. It CAN be done.
We were recently in an end game guild, and we were there a while. We went on HM runs and it was SHOCKING to me that the suggestions by Borella, BB, and others here WERENT being used. It flipped my brain to see a group that wasn't utilizing strategies that were spelled out here on the forum and they were FAILING and kept trying the same things! I tried to give my suggestions to the group... they were not looked upon favorably either. I was baffled even more. That is why I say that I KNOW it is possible for lesser groups, and the people here can only keep telling people to do the same thing... they cant follow you in game and smack you in the face with it......
Yes it would be good for more pug groups to run for people to farm their own gear. I have said it before in other threads bag stats and crafted/easy mode gear will get you to the point you are able to go and not be dead weight! I mean if you are one of the support classes you need even less to be viable.
Now of course ill admit I haven't been running anything. I have been farming my daililes on alts for ptokens, shells for stats for next level cap and just putting them aside, and improving some alt's gear. Yea gear is more scarce now then it has been... but if it isn't there today, I think "it might be tomorrow". I have been pretty laid back. When I want the gear with more of a passion ill start tryng to look for pug groups :p And when I see a piece I want, I know I am going to be paying a good price for it... I am ok with that.
