#1 I can tell you that you'r and my friendlist isn't representative in case when it comes to use macros. Cause different playstyle and different goals lead to what type of macroset you'll use.
I can say - I don't switch that much gear when it comes to 08/15 situations cause it's basicly not necessary cause we'r talking about a differenc of less than 1%. Under certain circumstances there's to change more gear.
#2 Changing gear with 1 or 10 macros doesn't have an impact of how often you blink - it's how fast you hit your macro and how good you manage to put items in a macro that would lead to blink and items who not. So basicly you have to hit 2 macros that would blink and one that doesn't. And I can hit 3 within one blink animation.
So there's no big deal esp. when it comes to a comparsion between what's ingame and what's possible due to 3'rd party tools. (btw. still forbidden - rtfm)
What I was saying is that with the possible automation that 3'rd party tools offer - people tend to use it cause of the "I want to get the last 0.001% of what's possible" without reconsidering what they are doing and what impact it would/could have.
My opinion - Use what's ingame and in case a supporter can't support cause he isn't using 3'rd party tools - who cares about him? And the same goes for every other job - in case the tank is about to die cause he massively blinks - not my fault. Not everyone is a FFXI-otaku/nerd. That's what's called TEAMWORK. And it's right - There is no I in Team.
