I can't give that any Inquisitor specific advice because my personal wisdom of the class in practice is limited to a sub level 30 inquis for now. I am interested in the lines of what SMITE touched on, though, and perhaps fill in a couple gaps on something I would strongly agree with. Don't take it the wrong way, but they might be genuinely trying to help, because they know the situation and conditions well. There are definately some characters with more equipment than brains to have ever figured out how to get said armor; regardless of method of acquisition, but thats neither here nor there.
I'd rather someone was trying to help me be better, even if wrong or slightly wrong in the reason or direction they point you in: at least you are aware that something may not be right, and have an idea at what to start looking at.
It drives me nuts to be in a new situation with a bunch of otherwise veteran players, indicate early on I don't have a clue about a particular area, and then later find out I did something wrong because I didn't know better in that situation. No one is blaming me in particular, necessarily, but it is what I did because I didn't know that made a straightforward situation a complex problem; or at worst, a failing condition. The worst part of it all is, I gave them an opportunity to offer advice, and made them aware that I dont know any better, but they couldnt be bothered to explain the key parts. Maybe a reluctance to say anything constructive in order to be -nice- about it, and so the saying the goes, if ya cant say anything nice dont say anything, right?
The groups that don't talk about this stuff are the first groups to struggle (aside ones that are clearly beyond their ability/capability: 1000 nekkid level five knomes marching on Vulak`Aerr will not be effective no matter how impressive nor how much they plan the timing of their little harm touches). Every group of random people that I have ever been with who talks through the puzzles and challenges often does much better than the ones that don't; even if we have all done it because we might not all do it the same, or place the same responsibilities on the same player/role. Even if our strategy doesnt work out, at least we have some idea why the tank did what they did, and why the mage did what they did; and hopefully, we learned something from that, and if necessary and able, can adjust. This strategy/planning would encompass coaching new players in the key areas.
I always found, that if I don't know, despite whatever my instinct tells me, do it they way they want the first time, and the second time, suggest trying what your instinct (or peraps a better source of info) told you. Its hard to argue with an example as clear as that.
