I agree with everything you stated, except the guard part. Unless the guard has 2 4 parts going over 90% DD, a temp will destroy them. Only because every temp in the game is a pussy and double debuffs while using reflect. When a temp does that 2 4 parts while being completely debuffed isn't enough damage to take them out.
Definitely agree with removing tds and holy wine, I can tank forever using them on a 45k hp guard as is. When I try to take out vit dekans, I can go up to 3-6k normals (16-20k KS) and most of the time won't kill them due to the insane amount of HP they have to begin with and tds/wine.
