Can't really think of any frontloaded bar that's as reliable/consistent for the AI to use.
Invoke seems the closest atm, but having Zhed run it before my char got to unlocking Norgu, I found I've had to babysit its invoke&attunement quite often. AI also feels way too clumsy with RoJ usage/placement without relatively excessive micro or specifically building my own bar for my liking (though ironically, still smarter than 9/10 of pug randoms); this is for my mesmer char, so SoH doesn't matter. I tried looking at necros, but the options are pretty crap for non-physicals. Never realised the AI options for caster players were so mediocre without mercs, since necro is my only pve caster char & ap/mop + spears/paras was an absolute no-brainer for that.
I can run whatever myself - keystone/surge/ap/EC/PI/etc. will spec for the zone or whatever mood I'm in, so just looking for a low maintainence pewpew hero bar to fill in #7 slot. The other AI bars are basically the main 5 from here or mm -> ST, but defensively tweaked like mop/splinter/PoD -> wow+rejuv/wowx2/IV (prefer drain/shatter to PoD generally tbh) & a burst monk. FB! can always be put on the SoS instead of #7 if necessary.
I'd also rather not change my Raz to me/ because I like the option of switching in the ST on demand.
