Ok so I've got it half working.
For those of you that didn't find my NavMesh it can be
[downloaded here]. I've added Grind markers at all the flags which makes the bot run from area to area and actually
hit targets in the process.
Pros:
1)Will Attack people and run from flag to flag
2)Don't look like an obvious bot
3)Receive rewards
The Bad:
1)It will not auto register for PVP.
2)At the start of the match it will try to run to Grind Markers while gates are closed.
3)My mesh covers everything except the starting areas (unless you're Immortal Flames) so you'll have to build the mesh for the starting area yourself.
4)Running of the cliff at the end of the starting point the bot does a weird jittery run.
5)You will not return automatically. You will have to respawn by yourself, however ressurection still works.
How to use:
1) Download my NavMesh from the link above.
2) Place it in your Minion Navigation folder.
3) Select Frontline and register.
4) Load the NavMesh while in Frontline
5) Have bot set to "Grind"
Enjoy.
