I also do not use vent or boss mods
That's odd, why would anyone purposely hinder themselves.
although I might bend on that for the right group.
Ok, well at least you seem willing to the idea if they are needed.
At this point if you need vent and boss mods to function then there is a serious player skill problem.
Nevermind, doesnt sound willing to "bend" at all.
There are a couple reason people are acting the way they are towards your post.
1) You are asking for people to trust your level of skill, when there is nothing to show for it. Only your word that you have done certain feats during certain times frames. No matter where you look, you will find people constantly asking for instances where your claims are true. Are you able to provide Logs or other measures to show how well you really do?
2)Tying in with the first point, you are asking people to change how they do things, when you are so opposed to changing yourself. There are countless reasons proving why voice communication software and an addon like DBM/BigWiggs is useful. The fact that you are so unwilling to compromise on something that is as small as one addon and a communication software does not look good for later on when there are more serious discussions.
3)Getting defensive about your skill is only hurting you. One person called you bad (there is still a lack of proof saying otherwise) then you assumed everyone else was calling you bad. Which wasnt necessarily the case. That being said, I have no problem calling you bad because your lack of consideration for other people. It is something incredibly small that provides so much information, and you are this unwilling to compromise on anything.
I mean how can you win if a mod can't tell you exactly what is going to happen.
Is this similar to how most people that PvP use Gladius, GladiatorLOSsa, InterruptionBar, HealersMustDie, or BattlegroundTargets? I mean all the top level arena people have to play with out any addons during tournaments, and you really dont need assistance with targeting healers or certain targets in Rated Battlegrounds. Just look at their mana and health. All these addons make your response time that much quicker. Being able to know which people on the other team have used their trinkets, is essential for setting up kills. Knowing when the other team has used major CDs offensively or defensively, is huge in knowing when to push in or when to pull back.
Is DBM needed? your argument is no, because of the in-game raid warning system, which is correct for LFR. Blizzard has come out and said it (this is what, 4 or so years ago now) that they design encounters with the mindset that DBM/BigWiggs is being used. Having more fights be pass/fail because of one shot mechanics or more personal responsibility is just two of the many ways they have adapted encounter design to DBM.
The conclusion I got of you, from this post was that you either:
-tried pulling the "Im a badass and do things with out any help" card which then back fired
-you really are as dense as you are coming off, and think people get offers to be carried by guilds after making such posts
-your computer is really that !@#$ty that it cant run wow with one addon, along side with a voice communication program
-or you are trolling
