If GW2 is really so bad it needs bots to make it worth playing, there's no point in playing at all.
There are a bajillion threads on ways to fix it. Either the solutions are too slow in being implemented or ArenaNet is happy with the design.
In such cases, its up to the community to find alternatives (and support those alternatives) to bringing the game in line.
And if bots are the means to the end, then go bots. GO-BOTS.
