Gear swapping was one thing in XI that was too annoying for me to participate in. Especially since some of my macro sets are full. I really hated how it became expected of everyone. I have 4 jobs I play very often. That's 4 sets of gear already. I wasn't going to make that 8 or more...I wouldn't have room if I wanted to anyways. I had some pieces that I'd wear in place of others on occasion - depending on what would work best for the situation, but I was never switching gear during battle.
On WHM it was annoying, everyone blinking all over the place, making it hard to target and heal them. I shouldn't have to download windower to make other people's blinking stop. You blink too much, I can't heal you, you die? Your fault. Simple as that.
I hate gear swapping. Always will. It's a silly practice. Every time I look at my boyfriend's full inentory, mog safe, storage, mog locker, mog satchel, and mog sack, I cringe.

I won't argue that gear swapping didn't make people more efficient/stronger/faster etc. It did.
I will argue that if people feel the need to do it that something is wrong.
It's something that is too annoying for me. I don't want to feel inferior to others in the game because I refuse to do something ridiculous like change my character's armor every few seconds.
