My suggestion is to make terraformers work less randomly and much more "mechanically" making it MUCH easier to use.
Change the way it transforms\creates\deletes blocks:
by making it start transforming\creating\deleting blocks from center and going to borders [Like a cube] once all blocks near the center are already transformed.
Making it check every 200+ ticks if there are available blocks to transform so it won't stop randomly like actual terraformer does, if almost all blocks in the area of effect are already transformed.
Change the way it uses EU :
Consume X EU to transform\create\delete a block, instead of randomly altering blocks depending on EU input.
Accept upgrades : Transformers increases EU/t usage [and speed] and Overclockers increases Area of Effect [and increases EU per block transformed]
Stop consuming EU once all blocks inside Area of Effect are transformed.
Change the Area of effect:
Alter a space of NxNxN (With N being a value, depending on TFBP and upgrades)
Change biome inside area of effect.
Blueprints have a tooltip showing EU usage, per block transformed\created\deleted.
Accept UUM as an amplifier (Like scrap does with UUM production).
Require an adjacent MFSU to work.
