I can honestly say this is tripe....I played 11, I had gear swap macros for every job I had leveled. (Quit @ Server merges time, well went pretty much non playing about 6 months before but still...)
Swapping gear 3 times for one action on an Odin fight as a SMN was stupid.
Swapping Gear on WHM Depending on which Cure I cast was dumb, swapping for Regen, Dumb.
Gear on THF going Evasion build for mass pullls/kiting made sense before pull, switching because I was stupid and took hate = dumb. Going Heca or Acc build for certain WS's again dumb....
Pulling a flute outta my ass cuz it enhance minuet = stupid, let alone the part where I have to jam it back in and pull a different flute out my ass cuz it boosted march or elegy or whatever.
I'm not gonna even mention the insanity with the Elemental Staves.
See where I'm going with this? Yea it's nice to min/max.....its not nice needing 30-40 gear pieces to play one job at a decent level. And thats without factoring in the skill elements.
I'm not saying this cuz I'm anti-XI. I'm saying this cuz its how it was, Gear swaps was nothing more than annoying, couldn't care less with regards to the min/max nor other peoples thoughts on "You need this item to play this job" mentality!
