Keep Macros

1. I play on the PS4, command bars are limited. Also for say BLM you'll never use blizzard 1 again once you get blizzard 3, but for doing level sync instances with friends, you can macro blizzard 1 after the blizzard 3 command and it'll go to blizzard 1 if blizzard 3 is unavailable or if you do not have the MP for it. Saves me a button slot.
2. So what if it's slow. For combat example above plus what others have mention.
3. RMT doesn't bother me anymore. I get maybe 1-2 different companies sent tells to me a day (2-4hrs of playtime a day), heck I don't even bother BListing them, just report and forget about them. I don't even run into RMT in the field any more.
