Bots are predictable as well as scale-able.
You can, eventually, set a bot to match your skill level and give you a genuine challenge. They are on demand and always available, and will stop the moment you get tired.
However, and I believe most importantly, you can make bots play the game the way it was meant to be played. No cheesy imbalanced loadout/class build/map position to contend with. No Meta-game fuckery. No net deck with 2000 bucks poured into it. If you like something, a bot will give you an even match rather than choose the hard counter to your selection 100% of the time, unless you want it to.
And yeah, PvP in general for MMO's is horrible anyways. You can't balance PvP in a game that even remotely respects its PvE without massive time investment.
