Sloshot, I apologize if you took offense. I didn't mean to insult, nor did I mean to attack. I did mean to be blunt. Your clarifications point out that you're basically doing what I suggested, whereas earlier posts were not so clear that you weren't just QQ'ing. Sometimes intent and meaning are lost in translation. Rereading my own post, it probably comes across a little more harshly than I intended. My real point was, don't worry about others expectations and play how you want with the time available to you.
I would like to follow up on one point, which is back on the original topic.
paraphrase of what Sloshot wrote:
So, if FD drinking works well for one player, and several others chime in to say...you MUST use expensive potions and such rather than what the OP was talking about. Not everyone can afford such luxuries.
Unfortunately, in this case, it's not really a matter of play style or doing what you want. When you're in a raid and everyone else is dependent on you, then it really is incumbent on you to perform at the peak. In the case of the OP, FD drinking is less than optimal and the real answer is to use consumables. I understand not everyone has a wealth of gold, but if you want to raid, there are costs that need to be paid. Skimping on them may be a play style, but it is one that guilds will probably not look too favorably on. You can try to say that they're trying to dictate how someone plays, but in a raid, they have every right to demand the best performance from their members. If someone doesn't have the time to farm/grind and can't afford certain things, then maybe raiding isn't an option. But, if you raid, come prepared. What would you say, for example, if a paladin came to raid and didn't buff anyone because the reagents were too expensive?
Don't get me wrong here. I'm not trying to say anyone should play a certain way. I'm not one to trumpet a particular build as the best, etc. I don't answer people's questions about MM builds by saying spec BM (for example). But, in this particular case, there really is a "correct" answer (aside from the exceptions in fights that others have pointed out).
