Does the main tank add the main group main assist as his first extended target as well?
Yep. He will tank all the mobs, and focus on the MA's target. With group damage going mostly / totally into that mob, he should not have to do much to hold the other targets, either.
For the last 5-8 levels 44-51, the bard has stopped mezzing. I am pretty sure if is because I have messed about with the ini's.
I don't know if the bot will automem a suitable mez spell in the defaultgem it uses. Mem the bard mez spell you want to use, make sure it's able to function against the mob level you want to use it on. If the mob is over the spell's level, the bard will just not bother to try.
Make sure the mob is not mez immune. First time in a zone, first mez attempt, mez immunes get flagged, and then the bot ignores them until next zone.
With the bot running, on the bard, type /bot usemez=1, it should echo the command in the MQ output window. Now the bard bot should attempt to bard mez whenever there is more than one mob on the hate list / extended target list - provided nothing else causes problems (no spell, immune, etc). If you want it off again, /bot usemez=0 should do it.
Not sure what places are any good these days, with modern game alterations, but seafury cyclops island, in ocean of tears ... they drop lots of cash items and plat, sort of. Easy place and often no-one is there. They aren't mobs you can AE though.
If I was trying to AE, I would not use the bot at all. At least on most of the toons. Maybe on the tank, maybe on the healer, but I don't think it's really set up for that kind of use.
It seems like you are just asking for someone to give you an AE macro set for toon X and Y. Maybe just how I read it. I'm not interested in providing that and I'm not sure what it has to do with this thread.
You can pause the bot, but only by running a macro. That macro might pause the bot and do other things, or it might just pause the bot. Pete did say he put in /bot pause but I could never get it to work.
To pause the bot via macro, include in the macro :
/declare MQ2BotPause bool outer 1
that will pause it.
Either /varset MQ2BotPause 0, to set it to 0 and unpause, or end the macro, which destroys the variable and unpauses the bot.
Otherwise you could just /bot off, which stops the bot, then /bot on, when you want to run it again. The bot on command does a /loadspells, which incurs about a second of delay. I at one point used that, hacked into the gribble macro that is around, to let the macro run it's pull routine, with the bot turned on when the toon got to camp, then off again to pull.
casting a spell a bunch of times can be done using
/casting "some spell" -recast|55
to cast it 55 times. look at the entry in the wiki for MQ2Cast. You have it loaded for the bot to work.
