What I currently bot with:
WD:with 100% community buff currently hitting 6bill exp per hr on Rifts
Rhen'ho-addling toads WD is just godly for botting as you have near perma CC on all mobs and your kill speed is FAST (I like to run poison pet WD with 60% poison buff)
Zuni: chest, feet, mojo
Blackthorn: Amulet, Legs, waist (to negate ground effects)
Theo & Tasker + Mask of Jeram
RoRG + Unity (Gems: BotT, Enforcer, Toxin all rank 30+)
you faceroll everything and ignore most ground effects which means you can bot 24/7 and never slow down for a death
Crusader: with 100% community buff currently hitting 8-9bill exp per hr on Rifts
I use a 57%cdr perma AK pony'sader which is just OP, nothing farms as well as pony'sader imo (not even M6-DH) as you can just faceroll everything, stand in any and every ground effect and never a chance of dying, (in trinity : I take off all avoid AoE, avoid Fire chains etc... and let it run 24/7) just need a decent Furnace to finish him off and farm even faster
Follower
Something I think is always overlooked
I advocate gearing up a Templar follower by the following:
as you are running UNITY then forget about any vitality on any follower items, reroll any vit into something useful preferably aspd or chc (this is because max CHD is 150% for follower)
Aim for:
max CHD on relic
max chc/aspd on rings/amulets
+10%dmg,7%Aspd & socket in weapon (preferably doombringer for the +%phys dmg)
10%chc & socket for shield
put max ruby gem in weapon & Shield
With this setup your templar will be at least 600k dps which helps you burn through rifts faster too (my current templar follower is 732k dps with my crusader and 597k dps for my WD)
this is a big free damage boost which people seem to overlook
