Maps and objectives are boring and lack of imagination

Just imagine if it was something like that

Objectives:
Escort and defend techprist so he can do his techpriesty things?
Load and shoot Leman Russ tank to blow up the gates?
Mark target for calling a Basilisk artillery barrage?
Defend a running train while on board?
Rescue Inquisition accolites?

Maps biomes:
Atoma’s moon - a paradise world with lakes, waterfalls, gardens and small rich city streets
Atoma Secundus/planet name - an ice hell planet
Atoma Tertius/planet name - a jungle death world

Grims and scripts are just lying on the floor? Like that? Not at plague altars or blasphemous totems, no puzzles for them?
