I don't think there's anything wrong with someone not wanting to post their strategy or build, even with this being a guide(even if it being on PLing is kinda lame) We all have the capacity to think and to plan. Play the game the way you want to play it. A guide is supposed to be just that. Something to Guide you...not something to base your game career off of. If you play that way, then you're playing the game for the wrong reasons.
With my gaming history, I would be considered a powergamer. Back then it more meant someone who strives to be the best that they can using the skills and tools they have available. Evidently today it means Who can best replicate a planned out strategy that everyone uses.
Anyway, this isn't the place for this post. I merely came to say that for this to be truely a guide to help people level(I'm not going to call it a PLing guide anymore), then his comments are completely viable regardless of whether he lays out exactly how to do it. Now if he's wrong, he's wrong and there's no point in beating him to death in the thread. I personally would never want to post my build on a char(unless it was an early version) except in parts...like saying I have this and this..and I can choose this or this..what would compliment best, type of thing.
But hell, I chose fly so I'm considered stupid from the get-go just because some people don't want to deal with the Z-axis movement.
Personally I like the idea of if I have to run, which isn't often, I can just zip straight up(assuming they can't or won't fly after me, even then all I'd have is the flyer) and not worry about dodging other groups of enemies
