Check here please so you can see what I do for each one. Still haven't uploaded them all but there's already a few.
In one evening I do without many problems from 7 to 13 Badges, depending on the time available (SP+UB in a bit less than 2 hours and Mecha 3 Bosses + 3 Bota bosses in about 2-2.5 more hours).

Trash in Mana Tombs is so easy, I'm not able to down first boss though and sometimes (don't ask me why ) I down the 2nd Boss and last one is easy.
Haven't tried last 2 Botanica bosses yet.
All the rest I haven't tried so far, having full geared the group I'm now finishing farming the 75k honor for the incoming S4.
But I guess there must be some more easy bosses like some mentioned in this post too .

Having problems with Thesp too :/ Where is that crack? Need because the other boss is very easy and I guess I'll love the last too .

Any hints for the Mecha boss that summons the fire elems? Thank you.
