As Garrisons will give you materials needed for everything and every profession being restricted to a daily cooldown, crafters will need to be consistent if they want to make gold off of their profession.
Couple that with the fact that there will be no flying mounts throughout the entire expansion (at least, that's how it is currently set by Blizzard), botters will have a hard time getting money off of node-farming. And with the catch-up system for professions, meaning, you can get ANY profession to 600 for almost no money, although it does take time as it is restricted with daily cooldowns, that means that old mats are useless unless you are really keen on making something from the old content.
BGs are also turning into rewards from chests along with honor gain, so you do not have to go through a bunch of farming to get geared for PvP, expect a lot less bots in BGs as well.
This is Blizzard's way of countering bots, as their lawsuit against Honorbuddy isn't going well, instead... they can just disable the click-to-move function, who the fuck uses that anyhow (except bots)?
Paraplegic gamers. they will never get rid of click to move.
