So....Champions that might make getting bulldozer worth something. This depends on if the opponent is A) Good...not likely at your level of comp. and B) what build they're running. It depends.

Barik is arguably the champion getting bulldozer is most needed for if he is running a self sustain build.
Ying can do a lot of healing and/or damage with her illusions.
Kinessa's mines reveal your position to the enemy team and are a great source of damage for kinessa...they need to be dealt with.

Saatis deployables can be a menace when placed correctly, as can Imanis warders field.

Io's luna is a great source of healing and needs to be taken out quickly...however, it isn't usually worth buying bulldozer for.
