Pointless.

Its either stupid checkpoints like complete a level or very convoluted achievements that cannot be acquired organically.

An example of the later is Meddling Kids in Project: Resistance.

The team must be super tight on coordination and deliberately set up their load out for that achievement alone and even then hope they play against Alex who doesn't know how to use her Ultimate right.

It's more likely that anyone who got that achievement has asked the mastermind before the start of the match to feed them that achievement.
